The Graded Response Differential Discrimination Model Accounting for Extreme Response Style

Extreme response style or, more generally, individual differences in response spacing have been shown to be an influential bias when analyzing questionnaire data. Recently a promising model adjusting for this bias — the differential discrimination model — has been proposed. An advantage to other related approaches is that the model can be fitted using standard structural equation modeling software. However, the model is designed for analyzing continuous item responses, whereas graded response formats are certainly more prominent in behavioral sciences. To resolve this limitation, the present article extends the differential discrimination model to analyzing graded responses. Empirical examples as well as a small simulation study are presented.     

On the generalization of attitude accessibility after repeated attitude expression

The more accessible an attitude is, the stronger is its influence on information processing and behavior. Accessibility can be increased through attitude rehearsal, but it remains unknown whether attitude rehearsal also affects the accessibility of related attitudes. To investigate this hypothesis, participants in an experimental condition repeatedly expressed their attitudes towards exemplars of several semantic categories during an evaluative categorization task. Participants in a control condition performed a non‐evaluative task with the same exemplars and evaluated unrelated attitude objects. After a 30‐minute interval, participants in the experimental condition were faster than controls to evaluate not only the original exemplars but also novel exemplars of the same categories. This finding suggests that the effect of attitude rehearsal on accessibility generalizes to attitudes towards untrained but semantically related attitude objects. © 2016 The Authors.

The go/no-go priming task: automatic evaluation and categorisation beyond response interference

The response-window version of a go/no-go (GNG) response priming task is introduced using both evaluative (Experiment 1) and animacy decision (Experiment 2). In each trial a cue indicates which target category should lead to a key-press. The target is preceded by either a congruent or incongruent prime. The standard priming task was added as well. Both tasks yielded robust priming effects. However, they differed regarding a signature of response activation paradigms, that is, the Gratton effect (i.e. smaller priming effects following incongruent trials compared to congruent trials), which is present in the standard task but absent in the GNG task. This indicates that effects found with the GNG task are caused by different processes compared to the standard task. Experiment 3 tested an alternative account to explain priming effects in the GNG task. By manipulating response biases, Experiment 3 provides evidence for this account.     

Which kind of attention is captured by cues with the relative target colour?

Most theories of visual search maintain that attention is selectively tuned to the attributes of the search target (e.g., orange). Conversely, according to the relational account, attention is biased to the relative feature of the target (e.g., redder). However, previous studies that supported the relational account mainly measured mean response times. Hence, the results might not reflect early, perceptual mechanisms (e.g., signal enhancement) but later, decision-based mechanisms (channel selection). The current study tested the relational account against feature-specific theories in a spatial cueing task, in which the targets were backward-masked, and target identification accuracy was measured. The first experiment corroborated earlier results, demonstrating that relational effects are due to signal enhancement. In the second experiment, we chose highly discriminable colours along the blue–red continuum, and obtained results that were more consistent with broad feature-specific rather than relational tuning. The implications of these findings for current theories of attention are discussed.     

Playing TETRIS for science counter-regulatory affective processing in a motivationally “hot” context

We adapted the computer game TETRIS to investigate the process of affective-motivational counter-regulation, that is, attentional biases for emotional stimuli that are in opposition to the momentary motivational focus. Counter-regulation is seen as a mechanism which should prevent escalation and impulsivity, and it should help to avoid becoming “locked up” in affective-motivational states. Accordingly, for a negative outcome focus condition (i.e., risk of losing a current high score), we hypothesized greater interference by positive distractors that were included in the game, whereas for a positive outcome focus (i.e., chance to improve one’s current high score), we hypothesized greater interference by negative distractors. Supporting our hypotheses, we found the predicted interactions between distractor valence and type of outcome focus.     

Aggressive Behavior of Passengers, Conflict Management Behavior, and Burnout Among Trolley Car Drivers

A sample of 96 trolley car drivers was used to investigate the relationship between aggressive behavior of passengers and burnout, the moderating effect of conflict management behavior of the drivers on this relationship; and the influence of burnout on customer-friendliness, passenger complaints, and absenteeism. The results show that aggressive behavior of passengers was related to all 3 burnout dimensions. The relationship of aggressive behavior of customers and professional efficacy was qualified by 2 significant interactions with 2 conflict management behavior styles: forcing and avoiding. The interactions showed that too much forcing as well as too much avoiding are related to less professional efficacy for drivers confronted with aggressive behavior. Passenger complaints were only related to less professional efficacy. The customer-friendliness of the drivers was related to less cynicism and more professional efficacy. Absenteeism was only related to exhaustion.     

Changing patterns of political participation of citizens of immigrant origin in the Brussels capital region: The October 2000 elections

The October 2000 elections did constitute a landmark for the political participation of immigrant origin citizens in the Brussels Capital Region. There was a remarkable increase of elected Belgian politicians of non-EU–mainly Moroccan–origin. In this contribution we want to discuss the changing patterns of political participation of immigrant origin citizens in the Brussels Capital Region as seen in the most recent local elections. We contextualize the electoral success of Turkish and (mainly) Moroccan politicians and the poor involvement of EU citizens in the recent elections. To this purpose, we also discuss the political situation in the bilingual region of Brussels, Belgian citizenship law and regulations for political participation of foreign residents.     

The locus of “memory displacement” is at least partially perceptual: Effects of velocity, expectation, friction, memory averaging, and weight

When observers are asked to localize the final position of a moving target, the judged position is usually displaced from the actual position. It has been suggested that mental processes derived from a number of invariant and noninvariant principles produce the mislocalization in memory. In this study, the effects of velocity, expectation, friction, memory averaging, and weight were reconsidered, and evidence was accumulated that supports the alternative view that the distortions arise to a large degree at a perceptual level. Effects of velocity and expectation were present when observers still perceived a persisting image of the target. It is suggested that the active reorienting of the perceptual organs explains the distortions. Furthermoremore, distortions of the perceived center of a visible stimulus may explain effects that have previously been attributed to memory averaging and mental analogues of weight. Thus, the locus of memory displacement is at least partially perceptual.     

The development of cued versus contextual conditioning in a predictable and an unpredictable human fear conditioning preparation

In this human fear conditioning study, the online development of conditioned US-expectancy to discrete cues and background contexts was measured in two groups. In the paired group (n=30), the CS was systematically followed by an aversive shock (US). In the unpaired group (n=30), CS and US were presented explicitly unpaired. Using US-expectancy ratings, we replicated the basic finding already illustrated in humans with startle modulation. In the paired group, the CS elicited more US-expectancy than the context, whereas in the unpaired group, the context elicited more US-expectancy than the CS. Interestingly, we also observed a trial-by-trial development of conditioning to the context in the unpaired group as indicated by a significant linear trend. This gradual development and the evidence for the role of US-expectancy in contextual fear add to the idea that cued and contextual fear rely on the same basic associative processes.     

Overgeneral autobiographical memory predicts diagnostic status in depression

Major depressive disorder (MDD) is characterised by difficulties in retrieving specific autobiographical memories, with a significant propensity towards categoric memories (i.e. memories of a summary type). Previous studies have demonstrated that this overgeneral memory is a valid predictor of the course of depression, with reduced specificity being associated with worse outcome. Most of these studies have employed continuous measures of depression to assess the course of the symptoms. This study investigated whether overgeneral memory also predicts clinical status at follow-up (i.e. whether patients still meet criteria for depression). Patients who fulfilled criteria for major depressive disorder were tested shortly after admission to the hospital and were retested some weeks later. It was found that lower levels of specificity or a higher number of categoric memories were associated with a higher probability of still being diagnosed with MDD. These memory variables outperformed other relevant indices, such as depression severity, rumination, level of self-esteem and dysfunctional attitudes.
