Internet and the support of psychology education

The Computers in Teaching Initiative (CTI) Centre for Psychology has been promoting the use of computers in psychology education for the last 5 years. The advent of the Internet and ubiquitous access to the World-Wide Web has the potential to revolutionize the way the teaching and learning of psychology can be supported. This paper describes how we are using the Web to support psychology education through information dissemination, through the provision of teaching resources, and through facilities for communication.     

Interactive Links Between Theory of Mind,Peer Victimization,and Reactive and Proactive Aggression

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.     

Investigating Interrelationships among Sales Training Evaluation Methods

Today numerous training options are available to sales organizations, and sales training teams use various means to report training effectiveness. This study utilizes Kirkpatrick’s (1959; 1960) training evaluation model and examines the interrelationships among its four levels of sales training evaluation (i.e., reactions, knowledge acquisition, behavior change, and organizational outcomes). Empirical results indicate that sales trainees’ use of training materials at work is positively related to achieving sales training outcomes, including improving (1) organizational commitment, (2) sales effectiveness, and (3) customer relations. Furthermore, trainees who had positive reactions to training were more likely to learn the material, and trainees with higher levels of knowledge retention were more likely to apply the material in the work environment. Implications are discussed that may aid sales firms to better evaluate training solutions provided by vendors and to develop more effective and accountable sales training efforts.     

The Confusion of Fear and Surprise: A Developmental Study of the Perceptual-Attentional Limitation Hypothesis Using Eye Movements

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.     

A daytime nap containing solely non-REM sleep enhances declarative but not procedural memory

The specialized role that sleep-specific brain physiology plays in memory processing is being rapidly clarified with a greater understanding of the dynamic, complex, and exquisitely orchestrated brain state that emerges during sleep. Behaviorally, the facilitative role of non-REM (NREM) sleep (primarily slow wave sleep) for declarative but not procedural memory performance in humans has been demonstrated in a number of nocturnal sleep studies. However, subjects in these studies were tested after periods of sleep that contained REM sleep in addition to NREM sleep, and comparison wake groups were subjected to mild sleep deprivation. To add some clarity to the findings of these nocturnal studies, we assessed performance on declarative and procedural memory tasks following a daytime training-retest interval containing either a short nap that included NREM without REM sleep, or wakefulness. Consistent with previous findings we show that, after a comparatively brief sleep episode, subjects that take a nap improve more on a declarative memory task than subjects that stay awake, but that improvement on a procedural memory task is the same regardless of whether subjects take a nap or remain awake. Slow wave sleep was the only sleep parameter to correlate positively with declarative memory improvement. These findings are discussed with reference to the general benefits of napping and within the broader context of a growing literature suggesting a role for NREM-specific physiology for the processing of declarative memory.     

The interaction of word frequency and word class: a test of the GO model's account of the missing-letter effect

When asked to detect target letters while reading a text, participants miss more letters in frequent function words than in less frequent content words. In this phenomenon, known as the missing-letter effect, two factors covary: word frequency and word class. According to the GO model, there should be an interaction between word class and word frequency with more omissions for function than for content words only among high-frequency words. This pattern would be due to the fact that function words could only assume a structure-supporting role if they are identified rapidly, which is only possible for high-frequency words. These predictions were tested by assessing omission rate for frequent and rare function and content words. Results lend support to the GO model with more omissions for frequent than for rare words, and more omissions for the function than for the content word among high-frequency words, but not among low-frequency words. These results were observed both in English (Experiment 1) and in French (Experiment 2).     

SCRIPTKELL: A tool for measuring cognitive effort and time processing in writing and other complex cognitive activities

We present SCRIPTKELL, a computer-assisted experimental tool that makes it possible to measure the time and cognitive effort allocated to the subprocesses of writing and other cognitive activities. SCRIPTKELL was designed to easily use and modulate Kellogg’s (1986) triple-task procedure, which consists of a combination of three tasks: a writing task (or another task), a reaction time task (auditory signal detection), and a directed retrospection task (after each signal detection during writing). We demonstrate how this tool can be used to address several novel empirical and theoretical issues. In sum, SCRIPTKELL should facilitate the flexible realization of experimental designs and the investigation of critical issues concerning the functional characteristics of complex cognitive activities.
