Positive effects of subclinical depression in prospective memory and ongoing tasks in young and old adults

Results reported in the literature show that depression can have either negative or neutral effects on prospective memory (PM). The goal of the present study was to broaden the analysis of depression-related effects on PM, with regard to the possibility that subclinical depression may have positive influence on PM. A total of 120 participants from four groups (young/old, subclinically depressed/non-depressed) completed event- and time-based PM tasks embedded in the linear orders task or stories task, respectively. In the event-based PM task no effects of depression were found, whereas depressed participants were more accurate in the time-based PM task, where higher monitoring during the last minute of the task was observed. It was also found that depressed participants built a mental model in the linear orders task more accurately than controls. Results of the present study are discussed with reference to the analytical rumination hypothesis.     

Self-motion perception influences number processing: evidence from a parity task

We investigated the role of horizontal body motion on the processing of numbers. We hypothesized that leftward self-motion leads to shifts in spatial attention and therefore facilitates the processing of small numbers, and vice versa, we expected that rightward self-motion facilitates the processing of large numbers. Participants were displaced by means of a motion platform during a parity judgment task. We found a systematic influence of self-motion direction on number processing, suggesting that the processing of numbers is intertwined with the processing of self-motion perception. The results differed from known spatial numerical compatibility effects in that self-motion exerted a differential influence on inner and outer numbers of the given interval. The results highlight the involvement of sensory body motion information in higher-order spatial cognition.

The relative importance of proactive behaviors and outcomes for predicting newcomer learning,well-being,and work engagement

New employees can accelerate and optimize their socialization by behaving proactively, although the key behaviors vary across studies. Recent research suggests that newcomer proactive behaviors influence socialization through the mediating effect of corresponding proactive outcomes. This may partly explain differences across studies, along with possible variations in the relative importance of specific proactive behaviors. This study investigates further the mediating role of proactive outcomes, and the relative importance of different proactive behaviors and proactive outcomes in predicting newcomer learning, well-being, and work engagement. Based on a sample of 176 temporary agency workers, support for the mediating role of proactive outcomes was found, although some proactive behaviors were effective in their own right. Relative importance analyses revealed that different proactive behaviors were important for different socialization criteria. Practical and theoretical implications of these findings are discussed.     

Evaluation des Screeninginstruments „Autism Mental Status Examination“

Background

Diagnostic procedures for autism spectrum disorders (ASD) include a thorough patient history, a clinical evaluation and the use of specific assessment tools, such as the autism diagnostic observation schedule (ADOS). For initial screening other instruments, such as questionnaires addressing the parents as well as affected children also exist. The autism mental status examination (AMSE) was developed to provide clinicians with a short, structured instrument to collate impressions after a clinical exploration. First studies from the USA showed a sensitivity and specificity which were satisfactory for a screening instrument with a cut-off score of 5.

Aim

The specificity and sensitivity of the German-speaking version of the AMSE for detection of ASD were investigated in a psychiatry cohort of children and adolescents.

Material and methods

This article reports the findings of a pilot study on the first use of the German version of the AMSE in 21 children who were evaluated for ASDs.

Results

The findings show a promising overlap with the ADOS and a satisfactory statistically significant correlation of 0.43.

Conclusion

The German version of the AMSE seems to be a promising screening instrument for ASDs; however, it cannot replace specific diagnostic tools.     

Multisensory processing of redundant information in go/no-go and choice responses

In multisensory research, faster responses are commonly observed when multimodal stimuli are presented, as compared to unimodal target presentations. This so-called redundant-signals effect can be explained by several frameworks, including separate-activation and coactivation models. The redundant-signals effect has been investigated in a large number of studies; however, most of those studies have been limited to the rejection of separate-activation models. Coactivation models have been analyzed in only a few studies, primarily using simple response tasks. Here, we investigated the mechanism of multisensory integration underlying go/no-go and choice responses to redundant auditory–visual stimuli. In the present study, the mean and variance of response times, as well as the accuracy rates of go/no-go and choice responses, were used to test a coactivation model based on the linear superposition of diffusion processes (Schwarz, 1994) within two absorbing barriers. The diffusion superposition model accurately describes the means and variances of response times as well as the proportions of correct responses observed in the two tasks. Linear superposition thus seems to be a general principle in the integration of redundant information provided by different sensory channels, and is not restricted to simple responses. The results connect existing theories of multisensory integration with theories on choice behavior.     

Evidence for precategorical extrinsic vowel normalization

Three experiments investigated whether extrinsic vowel normalization takes place largely at a categorical or a precategorical level of processing. Traditional vowel normalization effects in categorization were replicated in Experiment 1: Vowels taken from an [?]–[ε] continuum were more often interpreted as /?/ (which has a low first formant, F ₁) when the vowels were heard in contexts that had a raised F ₁ than when the contexts had a lowered F ₁. This was established with contexts that consisted of only two syllables. These short contexts were necessary for Experiment 2, a discrimination task that encouraged listeners to focus on the perceptual properties of vowels at a precategorical level. Vowel normalization was again found: Ambiguous vowels were more easily discriminated from an endpoint [ε] than from an endpoint [?] in a high-F ₁ context, whereas the opposite was true in a low-F ₁ context. Experiment 3 measured discriminability between pairs of steps along the [?]–[ε] continuum. Contextual influences were again found, but without discrimination peaks, contrary to what was predicted from the same participants’ categorization behavior. Extrinsic vowel normalization therefore appears to be a process that takes place at least in part at a precategorical processing level.     

Beyond prototypes and classical definitions: Evidence for a theory-based representation of emotion concepts

The question of how people represent emotions is eminently important for a number of different domains of psychological research. The present study tested the assumption that emotion concepts are represented similar to theories in that they are comprised of a set of causally interrelated features. Using emotional scenarios and investigating the emotion concepts of anger, anxiety, and sadness it was found that people's representations of emotion concepts essentially involved the representation of the causal relation of emotion features and that the causal status of a feature determined the feature's centrality in the concept. Moreover, people's representations of emotion concepts corresponded to basic assumptions of cognitive emotion theories, namely that cognitive appraisals cause other surface features of emotion, like expression and behaviour. By providing evidence for a theory-based representation, the present results show that the classical and the prototype approach are insufficient to model the representation of emotion concepts.
