Further evidence for the role of mode-independent short-term associations in spatial Simon effects

We examined the conditions under which short-term associations between stimuli and responses can produce spatial Simon effects. On location-relevant trials, participants gave neutral responses (i.e., they uttered the nonsense syllable "bee" or "boo") on the basis of whether the presented word had the meaning of "left" or "right." On location-irrelevant trials, they gave the same responses on the basis of the color of left and right squares. Performance on the location-irrelevant trials was affected by the match between the irrelevant location information and the location to which the correct response was assigned on the location-relevant trials. Experiment 1 showed that this extrinsic Simon effect was found only when the words on the location-relevant trials came from two different languages. In Experiment 2, we found an extrinsic Simon effect even when participants only received instructions about how to respond on location-relevant trials but no such trials were actually presented. Our findings suggest that task demands determine whether short-term associations are mode specific or mode independent and confirm that such associations can be set up as the result of instructions only.     

Subtle and blatant prejudice in western Europe

This paper develops, measures, and tests two types of intergroup prejudice—blatant and subtle. Blatant prejudice is the traditional, often studied form; it is hot, close and direct. Subtle prejudice is the modern form; it is cool, distant and indirect. Using data from seven independent national samples from western Europe, we constructed 10-item scales in four languages to measure each of these varieties of prejudice. We report the properties, structure and correlates of both scales across the seven samples, and make initial checks on their validity. The cross-nationally consistent results support the value of the blatant-subtle distinction as two varieties of prejudice. While they share many correlates, their distinctive differences suggest better specification of these correlates of prejudice. And the blatant-subtle distinction also aids in more precise specification of the effects of prejudice on attitudes toward immigrants. The paper closes with a normative interpretation of Subtle Prejudice.     

Categorization of sounds

The authors conducted 4 experiments to test the decision-bound, prototype, and distribution theories for the categorization of sounds. They used as stimuli sounds varying in either resonance frequency or duration. They created different experimental conditions by varying the variance and overlap of 2 stimulus distributions used in a training phase and varying the size of the stimulus continuum used in the subsequent test phase. When resonance frequency was the stimulus dimension, the pattern of categorization-function slopes was in accordance with the decision-bound theory. When duration was the stimulus dimension, however, the slope pattern gave partial support for the decision-bound and distribution theories. The authors introduce a new categorization model combining aspects of decision-bound and distribution theories that gives a superior account of the slope patterns across the 2 stimulus dimensions.     

On the Role of Vertical Texture Cues in Height Perception

When people judge height from the top looking down they tend to overestimate vertical distance. Initial findings suggest that this perceptual bias may be in part due to the experienced fear of falling. However, previous studies did not control for potentially relevant optical invariants, especially vertical texture gradient cues, that may inform such perceptual judgments. In this study, we examined to what degree texture gradient cues may account for the perceptual bias in height perception. To this end, in 2 different conditions in which vertical texture gradient cues were either present or absent, participants provided distance and size judgments from an elevated position (5.68 m) and from the ground. Results revealed a systematic overestimation of vertical extent and object size when judged from a height. Yet, the absence or presence of texture gradient cues did not differentially influence these judgments. Finally, although fear levels were reported to be larger at the elevated position than on the ground, fear levels did not correlate with the perceptual bias, thereby demanding further research into the mechanisms underlying the perceptual bias in height perception.     

Attention for emotional facial expressions in dysphoria: an eye-movement registration study

Former research demonstrated that depression is associated with dysfunctional attentional processing of emotional information. Most studies examined this bias by registration of response latencies. The present study employed an ecologically valid measurement of attentive processing, using eye-movement registration. Dysphoric and non-dysphoric participants viewed slides presenting sad, angry, happy and neutral facial expressions. For each type of expression, three components of visual attention were analysed: the relative fixation frequency, fixation time and glance duration. Attentional biases were also investigated for inverted facial expressions to ensure that they were not related to eye-catching facial features. Results indicated that non-dysphoric individuals were characterised by longer fixating and dwelling on happy faces. Dysphoric individuals demonstrated a longer dwelling on sad and neutral faces. These results were not found for inverted facial expressions. The present findings are in line with the assumption that depression is associated with a prolonged attentional elaboration on negative information.     

Cognitive coping and defense styles in patients with personality disorders

This study investigates the associations between cognitive coping (as measured with the Cognitive Emotion Regulation Questionnaire; CERQ), defense mechanisms (as measured with the Defense Style Questionnaire-60; DSQ-60) and personality disorders (PDs; as measured with the SIDP-IV interview) in a large sample of patients with PDs (n = 1,435). Explorative factor analyses indicated that the nine CERQ subscales can be clustered into three higher-order factors (adaptive coping, non-adaptive coping and external attribution style). When compared to a general population sample, the PD sample particularly scored higher on nonadaptive coping styles. A higher number of PDs was related to a particularly higher level of nonadaptive coping and less mature defensive functioning, but also to lower levels of adaptive coping and external attribution. This study is the first to suggest that three higher-order coping styles can be identified among PD patients, and that these coping styles are related to the presence and number of PDs.     

Justify your love: testing an online STI-risk communication intervention designed to promote condom use and STI-testing

The efficacy of a tailored, web-based intervention communicating the risks of sexually transmitted infections (STI) for heterosexual young adults was examined in a randomised, controlled trial. The main aims of the relationship-oriented intervention were to influence risk perceptions and to promote (maintenance of) condom use and STI-testing among young adults who reported being recently engaged in a heterosexual relationship. The intervention addressed risk perceptions, attitudes, normative beliefs, self-efficacy and skills related to condom use and STI-testing. Outcomes were compared immediately after the intervention (N = 171) and 3 months later (N = 115) to a non-tailored intervention group and to a control group. Cognitive and behavioural outcomes showed that the tailored intervention was efficacious in influencing perceived susceptibility to STI and STI-testing intentions immediately after the intervention, and in reducing rates of unprotected sex at 3 months.     

A functional role for the motor system in language understanding: evidence from theta-burst transcranial magnetic stimulation

Does language comprehension depend, in part, on neural systems for action? In previous studies, motor areas of the brain were activated when people read or listened to action verbs, but it remains unclear whether such activation is functionally relevant for comprehension. In the experiments reported here, we used off-line theta-burst transcranial magnetic stimulation to investigate whether a causal relationship exists between activity in premotor cortex and action-language understanding. Right-handed participants completed a lexical decision task, in which they read verbs describing manual actions typically performed with the dominant hand (e.g., "to throw," "to write") and verbs describing nonmanual actions (e.g., "to earn," "to wander"). Responses to manual-action verbs (but not to nonmanual-action verbs) were faster after stimulation of the hand area in left premotor cortex than after stimulation of the hand area in right premotor cortex. These results suggest that premotor cortex has a functional role in action-language understanding.
