Application of social identity theory in group therapy with stigmatized adults.

Social identity theory was applied in group therapy for adults with mild mental retardation. Social identity theory suggests that social group membership, also called collective identity, has an impact on self-esteem. Individuals will try to maintain self-esteem by viewing their social groups positively. This may not be possible for individuals who are members of a stigmatized group. However, it may be possible to enhance self-esteem by broadening one's awareness of collective identity. Furthermore, being able to positively view other individuals who are co-members of one's own stigmatized group can also have positive consequences for self-esteem. A clinical vignette demonstrates this process in group therapy. Results are discussed as being applicable to members of various stigmatized groups.     

More than meets the eye: Context effects in word identification

The influence of semantic context on word identification was examined using masked target displays. Related prime words enhanced a signal detection measure of sensitivity in making lexical decisions and in determining whether a probe word matched the target word. When line drawings were used as primes, a similar benefit was obtained with the probe task. Although these results suggest that contextual information affects perceptual encoding, this conclusion is questioned on the grounds that sensitivity in these tasks may be determined by independent contributions of perceptual and contextual information. The plausibility of this view is supported by a simulation of the experiments using a connectionist model in which perceptual and semantic information make independent contributions to word identification. The model also predicts results with two other analytic methods that have been used to argue for priming effects on perceptual encoding.     

Visual searh through word lists as a function of grade level,reading ability,and target repetition

Second-, fourth-, and sixth-grade students of high or low reading ability and college students carried out a visual-search task in which they scanned a list of 10 words, looking for a target word which was changed every trial or remained constant during an entire session. Search time increased linearly with serial position, consistent with a serial self-terminating model of visual search. The search rate increased from 3.3 words/sec in the second grade to 8.4 words/sec in college. Reading ability was not a significant factor in any comparisons. These results on the development of visual-search ability agree with others in showing that with increasing age there is a marked increase in search speed. However, retarded readers are as competent as their age peers on this task, suggesting that reading dysfunction must be traced to other deficiencies.     

Advanced training in child psychology: Key elements in offering a Doctor of Psychology (DPsych) programme in South Africa

The aim of this article is to propose some benchmarks for a Doctor of Psychology (DPsych) in advanced training in Child Psychology in South Africa, and to highlight key elements in offering such a programme. In doing so, we use as case illustration an existing DPsych programme currently being offered at the University of the Free State, South Africa. We consider advanced child psychology training to registered psychologists in the clinical, counselling and educational categories. The DPsych option encompasses clinical practice, research, training, selection, and student outcomes in the context of theory as well as evidence-based practices. A wider adoption of a DPsych, focusing on child psychology, would add value to the integration of the best available research and clinical expertise in child mental health care in South Africa.     

Linguistic Cues of Deception Across Multiple Language Groups in a Mock Crime Context

A recent study showed that specific linguistic and grammatical features of a technique commonly referred to as statement analysis are applicable across different language groups. One limitation of that study was that it used an eyewitness crime video paradigm, which might be different from writing a statement after committing an actual criminal act. We remedied that limitation by using a mock crime paradigm. In this study, three language groups (English, Spanish, and Chinese) produced statements after committing a mock crime, taking a check, in an experimental context. Certain linguistic features significantly discriminated truths from lies similarly across the different language groups, suggesting that statement analysis might be applicable as a reliable indicator of deception across languages.

Quantification of swim patterns in the morris water maze

Spatial learning and memory in rodents is most often assessed in the Morris water maze. Neurobiologists have to distinguish behavioral patterns to unravel underlying neuronal systems. We analyzed swim patterns of mice videotaped before and after training with a multitrial procedure in the water maze. In addition to traditional parameters, the animals’ position in relation to trained and other possible platform locations was estimated five times per second by an image analysis system. This parameter,cumulative distance to platform, was correlated with time spent in the platform quadrant but not with latency to and crossings of the platform location. We detected a subgroup of animals with concentric patterns within the group of spatial/persistent patterns. Random patterns were classified as well. Swim patterns before training were not predictive for the one after training. In summary, image analysis systems have made it very convenient to quantify behavior. Using their capacity, we have further improved the analysis of swim patterns, revealing animals’ different approaches to solve a problem.     

Impact of emotional appeal on non-profit advertising: A neurophysiological analysis

The number of Non-Profit Organisations (NPOs) has increased in the past years, and they rely on advertising to communicate their causes. Although the effectiveness of NPO advertising has been studied previously, there is still no consensus about which appeal (emotionally positive or negative) increases its effectiveness. On the other hand, the most prevalent research approaches to NPO advertising are traditional research methodologies based on declarative techniques. So, the purpose of this study is to identify which appeal (positive or negative) in NPO advertising is more effective at the three levels of effectiveness (perceptual or communicational effectiveness, psychological or attitudinal effectiveness and behavioural effectiveness), providing a new approach based on the analysis of consumers' unconscious responses to advertising. We conducted an experiment with 113 participants whose neurophysiological responses were evaluated through electroencephalogram (EEG) and eye tracking (ET) while they watched NPO advertisements with a randomly assigned emotional appeal (positive or negative). In addition, a survey revealed behavioural responses. The results showed that considering the psychological or attitudinal effectiveness, positively framed ads are more effective, as there is a positive effect on attitudes towards the ad and a higher positive emotional valence. On the other hand, in perceptual effectiveness, where attention is considered an important variable, the negatively framed ads showed more significant time in the area of interest (AOI) of the image area of the ad, and longer time in the AOI text was observed for positively framed ads. Furthermore, regarding behavioural effectiveness, negatively framed ads seem more effective in eliciting actual donations. The results suggest that a positive appeal is more effective in generating a more positive attitude and a positive emotional valence towards the advertisement, which could benefit the NPO in the long term. But a negative appeal is more effective if the goal is to achieve immediate donations.
