先定概率

先定概率

对于先定概率对回忆的影响的验证摘要:本实验是验证先定概率对回忆的影响的改进实验,实验的操作程序是基于杨志良先生的实验。

通过杨志良先生的实验得到如下结果,虽然实验结果以及绘图均与杨先生的实验结果存在差异,但本实验基本可以验证杨先生的实验,从而验证了先定概率对于记忆的影响,得出β值的改变独立于d’的改变,随着β越来越接近0,击中率越来越接近1,随着β越来越大,虚惊率越来越接近0。

ROC曲线里对角线越远,d’的值越大。

关键词:先定概率辨别力似然比信号噪音1引言信号检测论是信息论的一个分支,研究对象是信号传输系统中的信号接收部分。

在心理学领域中,由于人的感官以及分析综合的过程可以看做一个信系处理系统,这样我们就可以用新号检测论中的一些概念和方法来进行研究。

信号检测论有两个重要的指标:一个表示辨别的水平,不受情绪﹑期望﹑动机等因素的影响,通常用辨别力d’=Z虚惊-Z击中;另一个是表示反应偏向的指标,有两种计算方法,一种是似然比β,β=O击中-O虚惊,一种是报告标准C=[(I2-I1)/d’]﹡Z正确拒斥+I1。

信号检测论可以用于再认的记忆研究。

在应用信号检测论的再认实验中,将新(未见过的)、旧(已见过的)刺激分别视为噪音和信号,则d’的值低表是被试对新、旧不易鉴别;β或C值高表示被试对新、旧刺激判断标准松,反之,表示判断标准严。

本实验的目的在于(1)通过对杨志良先生的实验的验证,掌握信号检测论的基本理论,学会计算信号检测论指标d’、C、β;(2)学习绘制接受者操作特性曲线,了解信号检测论的用途;(3)了解信号的先定概率对再认回忆的影响。

2 方法2.1 被试被试十名2.2 仪器计算机2.3 材料西方,中国建筑图片共200张,分成4组,每组50张。

2.4 实验设计将四组图片的先定概率分别定出为不同的概率(成等差数列),对于每组图片,主视按定一种信号的先定概率给被试呈现一定的数目的图片,要求被试把他们当做“信号”记住。

in the rule.Especially if the response should be a failif something is found.For example you start with the actual question and then:"Doesthe document contain information that Aquiva is responsible for Security Review?If yesfail and explain why"User GuideDMD app allows you to run a group of prompts called Rules,grouped into Ruleset against Salesforce documents.Creating Rules and RulesetsCreating a RulesetRuleset serves as a framework for the AI and organizes individual rules within it.To create a new Ruleset,simply click on the arrow next to the Ruleset tab and choose'New Ruleset'from the dropdown menu.Next,complete the necessaryfields and save your changes:Name:Specify the name of the Ruleset.Description:Provide a brief description of the Ruleset.Context:Thisfield defines the context for the AI.Its content will be executed during the analysis phase to provide the AI with a better understanding of the purpose and objective of the Ruleset.Example:You are an experienced AI business specialist,and your primary task is to analyze Statement of Work(SOW)documents for compliance with specific rules.Your role is to provide accurate andconcise evaluations of the documents based on the selected rules and guidelines.Keep in mind the following:When a user sets a SOW document context,carefully analyze the content and compare it against the chosen rules.Use your advanced understanding of language and context to generate accurate and relevant responses.Remember,your goal is to assist users in ensuring their SOW documents are compliant with the selected rules,providing them with a reliable and efficient analysis.Creating a RuleA Rule represents a specific instruction that is executed within a Ruleset.To create a new Rule,follow these steps:Go to the Rule tab.1.Click on the arrow button next to the Rule tab.2.Select'New Rule'from the dropdown menu.3.Next,provide the necessary information for the Rule:●Name:Specify a name for the Rule.●Description:Provide a brief description of the Rule.●Content:Enter the prompt or instruction for the Rule.Ensure youfill in these details accurately to define the behavior and functionality of the Rule.Example:Does the document contain any information about payment deadline or schedule being15 or30days from invoice or bill receipt?If it does not,say that payment terms failedSee Prompts Recommendations section for more information about the prompts.Adding a Rule to A RulesetTo add a Rule to a Ruleset follow these steps:1.Go to the Ruleset you wish to modify.2.Locate the"Rules"section.3.Click on the"New"button within that section.A popup window will appear.In this window,do the following:1.Select the desired Rule from the available options.2.Check the checkbox next to the Ruleset where you want to add the Rule.3.Click the"Save"button tofinalize the addition.Removing a Rule from a RulesetGo to a Ruleset,scroll down to the‘Rules’,click on the arrow button new to the rule you want to remove from the ruleset and click Delete.Using Topic Tags to categorize Rules and RulesetsTopics are a standard Salesforce feature to easily categorize arbitrary records in Salesforce using simple word tags.You can add arbitrary Topic Tags to Rules and Ruleset to describethem a bit more detailedBefore you even think about where you use a Rule in an Analysis,you can mark it as●Related to a certain document type●Being a stable rule versus one you are still working on●If a rule is controversial and should not be used and enforces topic it“Controversial”After you added Topics you can use this categization tofilter Listviews and display only Rulesets that have or have not certain topics.This way you canfind rules easily for building new Rulesets and you can also keep your org cleaner by hiding unfinished,insatiable or controversial rules or rulesets from Default List Views.Check Documents by running an AnalysisTo perform an analysis on a document using the Document Checker component,follow these steps:1.Navigate to the record where the Document Checker component has been added.2.Within the record,locate the Document Checker component.3.The Document Checker will automatically scan and identify documents attached tothe record.4.Select thefile that you want to analyze from the identified documents.5.Click on the"Analyze this document"button to initiate the analysis process.6.A popup window will appear.In this window,select the desired Ruleset from theRulesetfield.7.Click the"Save"button to proceed with the analysis.A new page will open,providing you with the Analysis details.Please note that the analysis may take a few minutes to complete.As soon as the analysis is complete,you will receive a notification.However,please be aware that the application does not automatically refresh the page.Therefore,once youreceive the notification,manually refresh the page.After refreshing the page,you will notice that the status of the analysis has changed to either"Error"or"Success". "Results Summary"section contains information regarding the document analysis.This section provides an overview of the analysis outcomes.Navigate to the"Results"section to access detailed information about each Rule execution. This section will provide a breakdown of the analysis results based on individual Rules.If the list of results is extensive,click on the"View All"option to see the complete list of results.Click on the name of each result to obtain further details about that specific analysis outcome.This will allow you to gather more information and insights related to the result.On the Result record screen,you willfind detailed information about the execution of a Rule and the corresponding justification provided by the AI.Using Regression Test suiteRegression Test functionality was created to enable checking AI consistency in responding to specified rules.Each regression execution creates an Analysis record which can be compared to benchmark analysis where document analysis results are matching reality. Configure regression testIn the DMD application navigate to the Regression Tests tab.Create New Record andfill in required data:-Benchmark Analysis-point to perfect Analysis where AI is not hallucinating for any rule in set-ScheduleCron-schedule of regression test execution-information about how to specify CRON schedule can be found at Salesforce documentation-Using System Schedule-Status-leave unchanged-automatization is applied to thisfieldAfter a few executions of regression analyses in the report,users should be able tofind information about rule status distribution and response consistency.Below in the Results Summary section user canfind how each rule spread looks like.Cancel regression test executionRegression can be configured to execute until some date using CRON configuration. Another option is to create neverending schedule and when Rules are stable and responses are consistent admin can remove value from ScheduleCronfield.That operation should remove Scheduled jobs related to regression records from system setup. Export and Import RulesetsWithout using complicated tools like Dataloader you can easily export single or multiple Rulesets including their Rules into a JSONfile and import it into another org.To export a single Ruleset click Export on the Ruleset Record PageAfter a few seconds you browser will download a JSONfiles to your Downloads folder.If you open it you will see a structure of all your Rules.Thisfile can easily imported into any org with DMD installed by Clicking“Import…”on the Ruleset List ViewsSelect or Drop the JSON File to the Uploadfield and click Import.If everything goes as expected you see a Sucess message and new Rulesets.。

PROCESSING THE RADIOGRAPH. Neill Serman. Sept. 2000W + P. Chapter 6THE STAGES IN THE PRODUCTION OF THE RADIOGRAPHMany dentists who utilize manual processing, intentionally over expose patients and under process the radiograph in an attempt to save time resulting in radiographs that are inferior in diagnostic quality because of incomplete developing.When an X-ray film has been exposed, it must be processed in order to produce a permanent visible radiographic image that can be kept without deterioration for a number of years. Processing transforms the latent image into a visible image. The term for the several procedures that collectively produce the visible, permanent image is processing and consists of developing, rinsing, fixing, washing and drying procedures1. Exposure- Latent image created.2. Development - Converts latent image to black metallic silver.3. Wash [stop bath] - Removes excess developer.4. Fixing and Hardening - Dissolves out unexposed silver halide crystals.5. Washing- Removes products of processing.6. Dry- Removes water.For manual processing a floating thermometer, a timer and the time -temperature chart are essential.1. LATENT IMAGE FORMATION.The latent (invisible) image formation is the ionization of the exposed silver bromide crystals (by photon energy that emerges from the patient) occurring in the emulsion layer before processing occurs. The primary interaction with the bromide crystals is by Compton and photoelectric interactions, thereby knocking out electrons. Thus, a physical change occurs when the radiograph is exposed. When X-ray photons [or light photons] strike the silver bromide crystals in the emulsion, minute amounts of silver ions are formed on the surface of the crystal and bromine is liberated and is absorbed by the gelatin. Crystals are purposely constructed with electron traps (sensitivity specks) consisting of sulfur impurities but also because of the addition of silver iodide. Electrons are trapped by the sulfur in the sensitivity speck s giving it a negative charge. When this situation is created a latent image is produced in the film emulsion.AgBr + X-ray photons = Ag+ + Br-Silver bromide Silver ions + Bromine ionsThe latent image is formed by deposits of free (ionized) silver ions that cannot be seen or detected by any physical test devised as yet. It remains in the emulsion of the X-ray film until it is changed into a visible silver image by chemical processing procedures.The free electrons move through the crystal until they are attracted to a sensitivity site where they become trapped and impart a negative charge to the site.2. PROCESSING THE EXPOSED FILMExposed radiographs that contain a latent image should be processed as soon as possible as they are more sensitive to energy. Film packets are only to be opened in the darkroom or under safe-light conditions. [ in a daylight loader]The developer solution is the first solution into which the films are placed. The developer chemically reduces the energized ionized silver bromide crystals by donating electrons, removing the halides and precipitating metallic silver in the emulsion layer. The negative charge attracts positively charged free silver ions and is reduced to black metallic atoms. This precipitation corresponds to the black (radiolucent) areas on the radiograph.The concentration of the developer slowly weakens due to the number of films processed, [a chemical reaction] and with time by oxidation of the developer by exposure to air. Traditionally, the developer tank is placed on the left side of the other chemicals solutions 3. RINSING PROCESS / STOP BATH (WASHING)When the film is removed from the developer the gelatin emulsion is soft and swollen and contains chemicals which are removed by placing the film in a water bath. By rinsing the film in the water the soluble chemicals are removed, the development reaction is stopped, and the alkalinity of the residual developer is reduced. The unexposed silver halide crystals are not water soluble and will not be washed away.The film should be rinsed for 10-15 seconds in a bath of fresh, running water. The temperature of the water must be as close as possible to the temperature of the developer and fixer to avoid reticulation - uneven expansion and contractions of the emulsion layer. If this step were omitted, the alkaline developer retained by the film would soon neutralize the acid of the fixer. The fixing and hardening action of the fixer would be impaired and as a result, brown stains will be produced on the radiograph within a few weeks. Because the emulsion layer (gelatin) is soft when wet, the film scratches easily.Safe-light conditions must be maintained when transferring the film from the developer to the wash tank and then to the fixing tank to avoid fogging.For automatic processing there are "squeegy" rollers that remove the chemicals and thus the film goes from the developer solution straight into the fixer.4. FIXING.The acidic fixing solution removes the unexposed and undeveloped silver bromide crystals from the film emulsion and re-hardens the emulsion that has softened during the development process. For manual processing, if the film is placed in the developer solution for X amount of time it should be placed in the fixer for 2X and in the final rinse for 3Xamount of time. "X" is determined by the time-temperature chart. The ideal time to process radiographs in the developer is 680 F for 5 minutes.However, films may be removed from the fixing solution after five minutes for viewing only in cases of emergency - this procedure is known as wet reading \ viewing. The film must then be placed back in the fixer. If these unwanted silver bromide crystals are not removed, the resultant film will discolor after a few months. If the film is only partially fixed the film will turn brown in color with age.The gelatin protective coating is hardened by the potassium alum so the film will resist abrasion / scratching5. FINAL WASH.The purpose of the final wash is to remove residual fixer chemicals i.e. acid, thiosulfate and silver salts from the film. Insufficient washing results in the film turning brown as all the chemicals have not been washed away. If the temperature difference between developer and / OR fixer and water exceeds 15 F, there is a possibility of unequal swelling and shrinkage of the emulsion layer, commonly referred to as reticulation. Also, prolonged washing tends to make the emulsion soft, and it then scratches more easily.6. DRYING.In most offices, films are dried merely by hanging them on a rack in the darkroom above a drip tray designed to catch the run-off excess water. Others use a fan to dry the film. The fan should not blow directly on the films. Cabinet dryers are available which are equipped with a fan and heating elementsWet films are subject to damage from scratching and abrasion if not handled properly. If there is dust in the air, dirt will become easily embedded within the emulsion. Do not remove wet radiographs from their hangers until they are completely dryIn most darkrooms the developer will be in the left-hand tank as you face the tank, the water bath in the center and the fixing solution in the right-hand tank. The developer can be identified by its soapy feel, (alkali) the fixer by its vinegary odor when fresh and acid tasteAn area of less density, say the pulp, will allow greater penetration of X-rays; therefore more X rays will reach that part of the film. Thus more silver bromide crystals will be energized and more silver will precipitate to give a black or radiolucent outline to the pulp chamber. Areas that have received smaller amounts of radiation will have correspondingly less silver precipitated and will appear gray. Individually if a crystal is energized the whole crystal turns black. The silver bromide behind a gold crown, will precipitate no or very little silver as there was minimal energy reaching that area, and will appear white, or radiopaque on the radiograph. Gold and amalgam have high z values.The X-ray film is a delicate product, sensitive to many things, e.g. light photons, X-rays and gamma rays, pressure, to various gases and fumes, to heat and moisture and even aging causes a gradual change in it; known as fogging.PROCESSING CHEMICALS.A. DEVELOPER (Reducing Agent)Chemical Actiona) Hydroquinone brings out sharp contrast. The reducer acts slowlyIs a benzene product and made from dyesElon OR metol acts faster[phenidone - is now often used instead of elon or metol]This reaction can only occur in an alkaline mediumb) Alkalizer Provides alkaline medium in which the reducer[Accelerator] reacts. It softens and swells the gelatin emulsionNa2CO3 and attracts the exposed silver bromide crystalsc) Preservative Slows oxidation and therefore preserves the strengthNa. Sulfite of the other chemicals If not present the strength of theother chemicals would rapidly weaken. This explains thedarkening of the solutiond) Restrainer Restrains the developing agent from the strength. ThePot. Bromide. developing agent will deposit silver in the unexposed crystalsin the emulsion causing a silver deposit (fogging) on the film if therestrainer is not addede) Vehicle Provides a means for the chemicals in the developer toWater react (Ionize). Water helps to soften gelatinThe reaction does not occur unless alkalizer is present. The alkali "opens the doors" and permits the developing agents to enter the pores of the emulsion.If the lid is left off the developing tank, the preservative will be rapidly become exhausted by oxidation.In addition to the above a fungicide is added to prevent growth of fungi and a buffer is added to maintain the pH within specific limits.B. FIXING SOLUTIONCHEMICAL.ACTION.a. Fixing AgentSodium Thiosulfate (hypo) Removes unexposed crystalsAmmonium Thiosufate [Removes all crystals]b. Preservative Prevents deterioration of solution.Sodium sulfitec. Hardening agent Shrinks and hardens the gelatinPotassium alumd. Acidifier Provides acid medium. Alum reactsAcetic acid better in acid medium.Stops developing processe. Vehicle As above.WaterThe fixing agent removes all the silver halide crystals and therefore if a film is first placed into the fixer solution, the processed film will appear clear.TYPES OF PROCESSING.1. Manual2. Semi-automatic3. Fully automatic.a. without replenisherb. with replenisher.SOME DIFFERENCES BETWEEN MANUAL AND AUTOMATIC ROCESSING.1. No stop bath between developer and fixer as rollers remove the chemicals2. Higher temperatures for automatic processors. Therefore differentchemicals required3. Hardener placed in developer in automatic processors4. Additional hardener is added to the fixer solution.5. Because of the daylight-loader a darkroom is not required.6. Because of the heater in the automatic processor, the process is a "dry todry" process.Rapid processing solutions are used for emergencies and endo where time is of the essence. The film is developed for 15 - 20 seconds and fixed for a similar period of time. The films do not have the same amount of contrast and will discolor with time so they must still be fixed and washed correctly to minimize the discoloration.。

而一般的颜色——形状分类测验、威斯康辛卡片分类测验(也作为检测执行功能)、范畴测验等作为知觉测验的概括能力测验,PORTEUS迷津测验、流畅性测验、STROOP字色干扰测验、钉板测验、伦敦塔测验、失用症测验等作为知觉测验的执行功能与运动操作测验,有时也作为注意功能测验。

传统的测试方法时间分辨率差,缺乏特异性,对注意能力的评定要依赖记忆和视觉空间而难于分离出这种基础成分只能定性而不能精确定量地检测注意缺损。

通过开发相关系统和软件分析人类行为和生理信号等的方式来识别学习者注意力的方式是目前比较常用的方式。

相比于传统的注意力测试方式,这种方式能够实时洞察学习者注意力状态,帮助教育者实时掌握学习者的注意力,从而对教学有所掌控。

目前常用的测试持续性注意的方法工具有应用认知心理学软件DMDX、整合视听连续执行测试IVA-CPT、日本太田克也氏研发的持续性操作测验CPT、中南大学湘雅二医院精神卫生研究所编制的CPT软件、目前,国内心理学实验生成软件有:E-Prime、DMDX、Inquisit、 Presentation、DirectRT、SuperLab、Stim等。

TimeDX的测试步骤

Basic tests:

Select Video Mode Test

测试目的:确认显示卡正常驱动
测试目的:确认Millisecond Timer是否处于正常运作状态之下


Millisecond Timer Test

The High Performance Counter (HPC for short) is accurate to the displayed frequency and should be 1,192,180 Hz, it might be higher under Windows 2000
DMDX下载、安装、测试



假如你的机器没有Directx 5.0或更高的版本, 下载Directx 7.0并保存在Program files\dierectx\setup\; 双击该文件,程序会自 动安装; 下载dmdx软件包; 在Program files下创建一 个dmdx文件夹, 把dmdx解压在这个文件夹 中; 运行Timedx; 运行demos文件夹中的“features.rtf”文件, 测试和学习DMDX的功能。

Basic tests完毕后,在工作列上选择 Advanced tests
TimeDX的测试步骤

Advanced tests:


Time video mode (the Vertical Retrace SyncTest) 点选 Time video mode,等到出现对话窗后,先点选 Use Automatic Values,将 Step 3 Refresh Rate所测试出来的数 值应用在这个测试中,再点右下方的 Do test。做完以上动作 后,屏幕会出现很多跳动的数值,等到其中一个 msecs/retrace 的数值稳定 (变化小)后,按一下滑鼠就可 以回到对话窗,然后点 save last used values in registry储存 测试所得到的数值。这些数值表示的是这部电脑内部的性质, 而 TimeDX 能将这些数值储存下来,提供 DMDX 使用;所 以如果你要更换新的 Video mode 或你的电脑更换了新的显 示卡时,你就需要重新做上述的测试。 Tachistoscopic Acid Test 该测试的目的是确认电脑是否具有足够的记忆容量来执行 DMDX。
编程练习

用WordPad (Start -- Program Files -- Accessories -WordPad)为词汇判断实验写一个item file




实验开始前有个练习,4个练习项目(2 words, 2 nonwords) 实验有12个测试项目(6 words, 6 nonwords)。 每个项目呈现 前,屏幕中央都呈现一个注视点(fixation point) * ,呈现 500ms。靶子刺激呈现1000 ms。测试项目随机呈现。 练习开始前呈现指导语,而且在练习和正式实验之间要加以 文字提醒。 被试判断真词时按右Shift键,假词时按左Shift键。 实验结束后,呈现结束语"End of Experiment. Thank you for participating.“ 记录被试的反应时和错误率
DMASTR used to use completely nightmarish data files. Now everything is a lot simpler and the output files are a lot easier to work with. DMDX data files all have the suffix .azk
TimeDX的测试步骤

回到Basic test

Basic tests:

input test
ቤተ መጻሕፍቲ ባይዱ
做输入反应键等项目的测试,这个 test 有两个功能 确定实验所使用的「反应键」是可运作的 找出这些反应键在电脑里的定义码;编写DMDX的实验程 式时,你需要用这些定义码来设定程式的参数。
运行DMDX程序
DMDX的使用与操作
DMDX

DMDX


由Arizona大学的Jonathan和Ken Forster等人开发 是基于Win 32平台的刺激呈现软件系统 是Dmastr软件家族的一个成员,由基于DOS环境 的编成软件(DM and DMTG)扩展而来 主要用于言语、注意、记忆领域的实验程序的编制, 目前为世界上许多心理学实验中广泛使用的,使用 者涵盖了来自美国、英国、加拿大、中国等国高校 的心理学研究人员

启动DMDX 找到Item Files 开始实验 保存数据 (每运行一个被试,程序所采集的 数据都会累积地自动保存入相同的 .azk 文件 中)
How does DMDX work?
Item Files

Stimulus Files

These are simple files that contain a sequence of instructions telling the software (amongst other things)

把该item file以rich text format (.rtf)格式保存在一个文 件夹中,记住该文件的文件名。

TimeDX 测试

使用DMDX之前,使用者必须先在电脑中进行 TimeDX 的测试;这样 DMDX 才知道你所使用之 电脑的特性。 执行TimeDX测试前,请先关闭其它的应用程式。 在DMDX资料夹内含有一个TimeDX的捷径;点选 进入TimeDX后,在萤幕左上方的工作列上,点选 Basic Test,然后随着下面的步骤进行检测。

TimeDX的测试步骤

做完声音测试后,再回到Advanced tests

Tachistoscopic Acid Test

其目的是看看当声音材料数值设定后,电脑是否仍然运 作无误。 做声音时间值设定,程式会自动抓取可读的声音档案进 行(左右)喇叭的测试。

sound latency test

So what the heck is a tick? Simple answer:
Continuous Running
Without this, DMDX will pause after each item and wait for the subject to request the next item. This may be useful for working with patients, but most experiments tend to be continuous running with each item being played after the other

Refresh Rate test

测试目的:确认电脑屏幕刷新率。当你电脑的 video mode有更改 时,就该重做一次 refresh rate test。

注:TimeDX提供了多种 video mode,你不需要测试每一种 Video Mode; 你只需要选择其中一种,进行设定的 工作就可以了 。
