The Effects of Training on Perceptions of Sexual Harassment Allegations

This study of 176 college juniors examined the effects of respondent gender and sexual harassment training on the perceptions of what constitutes sexual harassment in the workplace. Variation in these perceptions, due to severity of the sexually oriented behavior, was also examined. Regardless of the subject's gender, individuals who 6 weeks earlier had seen a training film about sexual harassment rated severe sexually oriented work behaviors as more harassing than did individuals who had not seen the film. Additionally, males who had not seen the film rated ambiguous sexually oriented behaviors as less harassing than did males and females who had seen the film, and as less harassing than females who had not seen the film. Implications for the importance of training in addressing sexual harassment are discussed.     

Dissociations of language function in dementia: A case study

In this report we describe and attempt to characterize the deterioration in semantic knowledge occurring in a victim of a progressive dementing disease. The subject was unable to match even highly familiar naming words with their actual or pictured referents; instead, she consistently overextended verbal labels to closely associated distractors. The alteration in scope of referential meanings suggested by this overextension effect was apparently related to a breakdown in the structure of underlying categories. On a nonverbal match-to-sample procedure, for example, dogs were treated as exemplars of the cat family. Evidence for the breakdown of semantic knowledge was not limited to picture labeling paradigms. Thus, we found that the subject was unable to utilize semantic context in the written disambiguation of spoken homophones but could, at the same time, use even minimal syntactic cues as the basis for proper lexical selection. This last result was consistent with other lines of evidence pointing to the relative preservation of syntactic operations, in marked contrast to the semantic loss. The importance of this dissociation of function in organic pathology is considered from a number of perspectives, including its relevance to models of language organization in the brain.     

ALTERING SHOPPERS' SUPERMARKET PURCHASES TO FIT NUTRITIONAL GUIDELINES: AN INTERACTIVE INFORMATION SYSTEM

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.     

Decomposition can harm the accuracy of behavioural frequency reports

In survey research, the use of decomposition can lead to pronounced reporting errors as seen by overreporting and overall reporting error. A total of 87 subjects answered either decomposed or undecomposed questions concerning telephone calls made by them while at work. The questionnaire conditions varied the length of the reference period (1 week or 6 months), and the type of call (local or long‐distance). Decomposition conditions introduced either spatial or temporal cues. In all comparisons, decomposed questions increased overreporting bias relative to undecomposed questions. In addition, undecomposed questions with a 1‐week reference period led to increased overreporting bias in comparison to undecomposed/6‐month questions. Results are consistent with a category split estimation model in which smaller categories are predicted to lead to overreporting, and larger categories to underreporting. Decomposition is not recommended for gaining retrospective reports of non‐distinctive, frequent events. Copyright © 2000 John Wiley & Sons, Ltd.     

Decoding human brain activity during real-world experiences

The human brain evolved to function and survive in a highly stimulating, complex and fast-changing world. Attempting to ascertain the neural substrates of operating in naturalistic contexts represents a huge challenge. Recently, however, researchers have begun to use several innovative analysis methods to interrogate functional magnetic resonance imaging (fMRI) data collected during dynamic naturalistic tasks. Central to these new developments is the inventive approach taken to segregating neural activity linked to specific events within the overall continuous stream of complex stimulation. In this review, we discuss the recent literature, detailing the key studies and their methods. These analytical techniques can be applied in a wide range of cognitive domains and, thus, offer exciting new opportunities for gaining insights into the brain bases of thoughts and behaviours in the real-world setting where they normally occur.     

Deconstructing episodic memory with construction

It has recently been observed that the brain network supporting recall of episodic memories shares much in common with other cognitive functions such as episodic future thinking, navigation and theory of mind. It has been speculated that 'self-projection' is the key common process. However, in this Opinion article, we note that other functions (e.g. imagining fictitious experiences) not explicitly connected to either the self or a subjective sense of time, activate a similar brain network. Hence, we argue that the process of 'scene construction' is better able to account for the commonalities in the brain areas engaged by an extended range of disparate functions. In light of this, we re-evaluate our understanding of episodic memory, the processes underpinning it and other related cognitive functions.
