Measurement is a critical aspect of the scientific process. If measurement systems are not accurate and precise, the findings of experiments will most likely be spurious. In applied behavior analysis, the most prevalent form of measurement is human observation with automated measurement being used sporadically. Automated measurement is generally more accurate as it minimizes recording error. This paper reviews some of the common measurement systems currently in use and examines some new technologies that may expand the use of automated recording in the future.

Retrograde amnesia following disruptions of hippocampal function is often temporally graded, with recent memories being more impaired. Evidence supports the existence of one or more neocortical long-term memory storage/retrieval site(s). Neurotoxic lesions of the medial prefrontal cortex (mPFC) or the dorsal hippocampus (DH) were made 1 day or 200 days following trace fear conditioning. Recently encoded trace fear memories were most disrupted by DH lesions, while remotely encoded trace and contextual memories were most disrupted by mPFC lesions. These data strongly support the consolidation theory of hippocampus function and implicate the mPFC as a site of long-term memory storage/retrieval. 相似文献

This fMRI study investigated the neural correlates of reward-related trial-and-error learning in association with changing degrees of stimulus-outcome predictabilities. We found that decreasing predictability was associated with increasing activation in a frontoparietal network. Only maximum predictability was associated with signal decreases across the learning process. The receipt of monetary reward revealed activation in the striatum and associated frontoparietal regions. Present data indicate that during reward-related learning, high uncertainty forces areas relevant for cognitive control to remain activated. In contrast, learning on the basis of predictable stimulus-outcome associations enables the brain to reduce resources in association with the processes of prediction. 相似文献

Assessment methods relying on biased or inaccurate retrospective recall may distort knowledge about the nature of disorders and lead to faulty clinical inferences. Despite concerns about the accuracy of retrospective recall in general and in particular with obsessive–compulsive disorder (OCD) patients, the accuracy of retrospective recall for one's own symptoms assessed in vivo is unknown in this population. This study used a prospective ecological momentary assessment (EMA) methodology to create a criterion against which to assess recall accuracy in OCD patients. Although results indicated that patients’ retrospective recall of OCD symptoms was fairly accurate, they consistently overestimated the magnitude of OCD symptom covariation with non-OCD facets (e.g., sleep duration, contemporaneous stress level, etc.). Findings suggest that even when recall of OCD symptoms is accurate, patients may be inaccurate in estimating symptom covariation. The findings have implications for the research, case conceptualization, and assessment of OCD, and may extend to other disorders. 相似文献

We review the debate over behavior, gender and classroom placement in ability groups for kindergartners. Using vignettes we
vary children’s gender in three ways; male, female, or unspecified gender and also describe them as behaving well, average,
or misbehaving. Our aim is to probe how much gender and behavior matter with respect to mock reading group placement. The
design allows us to see if depicted behavior affects placement when every vignette child is described as possessing the same,
average ability. After reading vignettes that vary gender and behavior, but not ability, respondents are directed to assign
the portrayed child to a high, medium or low reading group. While depicted behavior strongly affects reading group placement,
gender is not a significant predictor.

Facial race and sex cues can influence the magnitude of the happy categorisation advantage. It has been proposed that implicit race or sex based evaluations drive this influence. Within this account a uniform influence of social category cues on the happy categorisation advantage should be observed for all negative expressions. Support has been shown with angry and sad expressions but evidence to the contrary has been found for fearful expressions. To determine the generality of the evaluative congruence account, participants categorised happiness with either sadness, fear, or surprise displayed on White male as well as White female, Black male, or Black female faces across three experiments. Faster categorisation of happy than negative expressions was observed for female faces when presented among White male faces, and for White male faces when presented among Black male faces. These results support the evaluative congruence account when both positive and negative expressions are presented. 相似文献

We investigated the construction of gender in chat groups. Four unacquainted persons chatted in two gender-anonymous conditions and a non-anonymous control condition. In one anonymous condition, the gender focus was made salient. The other groups did not know about the gender focus. All participants had to guess the gender of the others and give reasons for their decisions. Results suggest that (a) overall, 2/3 of gender guesses fit the sex category of the targets, (b) gender anonymity was more comfortable for women, (c) participants used mostly gender-stereotypic cues to infer gender, however, men and women used syntactic, semantic, and pragmatic cues (with different predictive value) to different degrees, (d) conversational behavior varied depending on gender anonymity, and (e) degree of gender salience was irrelevant for the use of gender as an organizing category. 相似文献

In the current study, we addressed modality-specificity of the flexibility of cognitive control. We compared performance in single-task and mixed-tasks blocks between blocked auditory and visual stimuli assessing alternation costs (single vs. mixed). Mixed blocks comprised task switches only. The tasks consisted of numerical parity, magnitude, and distance judgments about numbers between one and nine without five. A cue indicated the relevant task. The cue–stimulus interval was varied (short vs. long interval) to examine preparation effects. The results indicated higher response times (RTs) and error rates (ERs) in mixed- vs. single-tasks blocks. The alternation costs in ERs were larger for auditory compared to visual stimulus presentation. Moreover, the reduction of RT alternation costs based on increased preparation time was more pronounced for the auditory modality compared to the visual modality. These results suggest a modality-specific influence on processes involved in maintaining and updating task sets in working memory. 相似文献

Statements’ rated truth increases when people encounter them repeatedly. Processing fluency is a central variable to explain this truth effect. However, people experience processing fluency positively, and these positive experiences might cause the truth effect. Three studies investigated positivity and fluency influences on the truth effect. Study 1 found correlations between elicited positive feelings and rated truth. Study 2 replicated the repetition-based truth effect, but positivity did not influence the effect. Study 3 conveyed positive and negative correlations between positivity and truth in a learning phase. We again replicated the truth effect, but positivity only influenced judgments for easy statements in the learning phase. Thus, across three studies, we found positivity effects on rated truth, but not on the repetition-based truth effect: We conclude that positivity does not explain the standard truth effect, but the role of positive experiences for truth judgments deserves further investigation. 相似文献

Quantitative research on levels of depression and gender dysphoria in drag populations is lacking. It is possible that this lack occurs because researchers tend to include drag queens within transgender samples. Such sampling practices may result in inaccurate assumptions about drag queen populations. This study established rates of depression and gender dysphoria in a sample of self-identified cisgender drag queens. Participants reported low levels of gender dysphoria and significantly lower levels of depression than have been found among trans women, however, these participants presented with higher rates of depression than have been found among gay men who do not perform drag. Higher rates of involvement in drag performance were positively correlated with depression and negatively correlated with gender dysphoria. Results indicate that self-identified cisgender drag queens are unlikely to experience gender dysphoria and are less depressed than samples of trans women. The researchers discuss implications and future directions for mental health practitioners. 相似文献
