Is Implicit Personality Theory illusory? Armchair criticism versus replicated empirical research

The Tzeng and Tzeng (1982) criticisms of the assumptions underlying the Jackson, Chan, and Stricker (1979) study of Implicit Personality Theory fail to take account of the relevant empirical data. For example, the key contention of Tzeng and Tzeng–that the measures of judged and empirical trait-co-occurrence used by Jackson et al. were not comparable–is contradicted by replicated findings which establish that the two are substantially and consistently related, results for which Tzeng and Tzeng offer no alternative explanation. In short, Tzeng and Tzeng have not demonstrated that their criticisms have any real substance. Hence, none of the Jackson et al. results and conclusions, including those questioning the conditional probability index as a measure of empirical co-occurrence and those supporting the validity of Implicit Personality Theory, are affected or changed.     

Do chickens (Gallus gallus f. domestica) decompose visual figures?

To investigate whether learning to discriminate between visual compound stimuli depends on decomposing them into constituting features, hens were first trained to discriminate four features (red, green, horizontal, vertical) from two dimensions (colour, line orientation). After acquisition, hens were trained with compound stimuli made up from these dimensions in two ways: a separable (line on a coloured background) stimulus and an integral one (coloured line). This compound training included a reversal of reinforcement of only one of the two dimensions (half-reversal). After having achieved the compound stimulus discrimination, a second dimensional training identical to the first was performed. Finally, in the second compound training the other dimension was reversed. Two major results were found: (1) an interaction between the dimension reversed and the type of compound stimulus: in compound training with colour reversal, separable compound stimuli were discriminated worse than integral compounds and vice versa in compound training with line orientation reversed. (2) Performance in the second compound training was worse than in the first one. The first result points to a similar mode of processing for separable and integral compounds, whereas the second result shows that the whole stimulus is psychologically superior to its constituting features. Experiment 2 repeated experiment 1 using line orientation stimuli of reversed line and background brightness. Nevertheless, the results were similar to experiment 1. Results are discussed in the framework of a configural exemplar theory of discrimination that assumes the representation of the whole stimulus situation combined with transfer based on a measure of overall similarity.     

Decision-making impairments in patients with Parkinson's disease

A high percentage of Parkinson's disease (PD) patients show cognitive impairments in addition to the cardinal motor symptoms. These deficits primarily concern executive functions most probably linked to dysfunctions in prefrontal regions due to decreased dopaminergic transmission in fronto-striatal loops. To investigate possible associations between decision-making and executive functions in PD, we examined 20 non-demented PD patients and 20 healthy control subjects with a neuropsychological test battery and the Game of Dice Task. In this computerised decision-making task, the rules for gains and losses and the winning probabilities are obvious and stable. Thus, strategic components besides feedback processing might influence decision-making in this task. We found that PD patients were impaired in the Game of Dice task performance and that the frequency of disadvantageous choices correlated with both executive functions and feedback processing. We suggest that decision-making deficits of PD patients in explicit gambling situations might be associated with dysfunctions in two different fronto-striatal loops: the limbic-orbitofrontal-striatal loop, involved in feedback processing, and the dorsolateral prefrontal-striatal loop, involved in executive functions.     

Reducing the drop-out rates of at-risk high school students: the Effective Learning Program (ELP)

The purpose of the present study was to evaluate the effectiveness of the Effective Learning Program (ELP) with students who are at high risk for dropping out of high school. The intervention sought to change external control expectancies to more internal ones, improve students' skills in building relationships with peers and adults, and increase graduation rates. Thirty-eight students considered at risk for dropping out of high school received the intervention. In addition, ELP-eligible students who did not receive the ELP intervention (n = 36) and regular education students (n = 50) from the same high school were compared with the students who received the ELP. A significantly greater percentage of ELP students graduated, became more internally controlled, achieved more as shown by standardized tests, and developed greater social skills and better relationships than their ELP-eligible but nonparticipating peers. The authors suggest that researchers identify which aspects of the ELP are responsible for the improvement in retention, achievement, and personal attributes.     

Developmental dyslexia in different languages: language-specific or universal?

Most of the research on developmental dyslexia comes from English-speaking countries. However, there is accumulating evidence that learning to read English is harder than learning to read other European orthographies (Seymour, Aro, & Erskine, 2003). These findings therefore suggest the need to determine whether the main English findings concerning dyslexia can be generalized to other European orthographies, all of which have less irregular spelling-to-sound correspondences than English. To do this, we conducted a study with German- and English-speaking children (n=149) in which we investigated a number of theoretically important marker effects of the reading process. The results clearly show that the similarities between dyslexic readers using different orthographies are far bigger than their differences. That is, dyslexics in both countries exhibit a reading speed deficit, a nonword reading deficit that is greater than their word reading deficit, and an extremely slow and serial phonological decoding mechanism. These problems were of similar size across orthographies and persisted even with respect to younger readers that were at the same reading level. Both groups showed that they could process larger orthographic units. However, the use of this information to supplement grapheme-phoneme decoding was not fully efficient for the English dyslexics.     

General self-efficacy,dental anxiety and multiple fears among 20-year-olds in Norway

This paper examines the extent to which low general self-efficacy and painful dental and medical experiences are related to dental anxiety, multiple fears and to avoidance of dental care. A total of 754 20-year-olds completed a series of questionnaires, including the General Self-efficacy Scale (GSE), Geer Fear Scale (GFS) and Dental Fear Survey (DFS). Females had lower self-efficacy, higher dental anxiety and higher scores on the GFS than males. Multivariate analyses (linear stepwise regression) indicated that painful dental experiences, a high score on the GFS and negative opinions about own dental health explained 37% of the variance in DFS scores. Self-efficacy had no predictive power for dental anxiety, and only dental anxiety had predictive power for dental avoidance behavior. Thirty-eight percent of the total variance in GFS scores was explained by the following variables: being a female, high dental anxiety (DFS), low general self-efficacy (GSE) and low educational level of the mother.

Strukturbezogene Psychotherapie

Structure-oriented psychotherapy is a variant method of the psychodynamic therapeutic procedure concerned with the therapeutic encouragement of insufficiently available structural abilities of patients, in contrast to realization of conflicts. This form of psychotherapy is based on the definitions of Operationalized Psychodynamic Diagnostics (OPD) and the diagnostic and therapeutic studies carried out with this method in the comprehension of structural functions and levels. The therapeutic approach and the therapeutic attitude were formulated with respect to the developmental psychological aspects of early relationship disorders. The method is indicated where, for example in severe personality disorders the clinical picture is determined by the structural problems of self-regulation and relationship formation. In this case the patient should first be actively stabilized in order to then increasingly transfer responsibility for self-regulation and way of life and to work these out together. The individual stages of the therapeutic process and the special interventions against the background of a development promoting, parental-like therapeutic attitude will be described.     

Acceptance of sexual aggression myths in a representative sample of German residents

A representative sample of German residents (N = 5397) was surveyed with the aim of studying their acceptance of contemporary rape myths (RMA), using items from the Acceptance of Modern Myths About Sexual Aggression Scale [AMMSA; Gerger et al., 2007] in relation to demographic variables (e.g., gender, age), intolerant belief systems (e.g., sexism, islamophobia), the ideologies of rightwing authoritarianism (RWA), and social dominance orientation (SDO), as well as gender identification. Age showed a U-shaped relationship with RMA, whereas gender was unrelated to RMA. For men (women), greater identification with their gender was associated with higher (lower) RMA. Substantial correlations of RMA with intolerant belief systems support the idea of a schema of intolerance. Although RWA and SDO were both related to RMA, only RWA explained unique variance beyond the effects of intolerant belief systems. Results are discussed in comparison to prior studies using mainly student samples.
