Why eye movements and perceptual factors have to be controlled in studies on "representational momentum"

In order to study memory of the final position of a smoothly moving target, Hubbard (e.g., Hubbard and Bharucha, 1988) presented smooth stimulus motion and used motor responses. In contrast, Freyd (e.g., Freyd and Finke, 1984) presented implied stimulus motion and used the method of constant stimuli. The same forward error was observed in both paradigms. However, the processes underlying the error may be very different. When smooth stimulus motion is followed by smooth pursuit eye movements, the forward error is associated with asynchronous processing of retinal and extraretinal information. In the absence of eye movements, no forward displacement is observed with smooth motion. In contrast, implied motion produces a forward error even without eye movements, suggesting that observers extrapolate the next target step when successive target presentations are far apart. Finally, motor responses produce errors that are not observed with perceptual judgments, indicating that the motor system may compensate for neuronal latencies.     

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.     

Unintentional processing of motivational valence

Recent motivational affective priming studies (Moors & De Houwer, 2001; Moors, De Houwer, & Eelen, 2004) showed that primes that indicate success on a goal-inducing task facilitate positive target responses whereas primes that indicate failure on that task facilitate negative target responses. In the current studies, we examined whether these priming effects depend on consciously intentional processing of the motivational valence of the primes. In Experiment 1, the outcome of success or failure was presented not only immediately before the target (i.e., the prime) but also a second time after the target response. This should encourage participants to ignore the prime. In Experiment 2, participants were asked to respond to the targets within 600 ms after target onset. As a result, participants had little opportunity to process the motivational prime valence in a consciously intentional way. Nevertheless, strong affective priming effects were found in both studies. These results provide additional support for the claim that motivational valence can be processed without the conscious intention to do so.     

Making Sense of a New Employment Relationship: Psychological Contract‐Related Information Seeking and the Role of Work Values and Locus of Control

This paper explores the information‐seeking behaviors newcomers engage in relating to their psychological contract and addresses the impact of work values (autonomy, advancement, group orientation and economic rewards) and work locus of control (LOC). We propose that these individual characteristics could explain differences in the frequency with which newcomers search for information about the promises their employer has made to them. A two‐wave longitudinal study was conducted in which 527 newcomers from eight organizations participated. The results largely support the proposed relationships between work values and contract‐related information seeking, while the relation between work LOC and contract‐related information seeking is rather weak. Implications for psychological contract formation are discussed.     

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.     

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.     

A sentence completion procedure as an alternative to the Autobiographical Memory Test for assessing overgeneral memory in non-clinical populations

Overgeneral memory (OGM) has been proposed as a vulnerability factor for depression (Williams et al., 2007) or depressive reactivity to stressful life-events (e.g., Gibbs & Rude, 2004). Traditionally, a cue word procedure known as the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986) is used to assess OGM. Although frequently and validly used in clinical populations, there is evidence suggesting that the AMT is insufficiently sensitive to measure OGM in non-clinical groups. Study 1 evaluated the usefulness of a sentence completion method to assess OGM in non-clinical groups, as an alternative to the AMT. Participants were 197 students who completed the AMT, the Sentence Completion for Events from the Past Test (SCEPT), a depression measure, and visual analogue scales assessing ruminative thinking. Results showed that the mean proportion of overgeneral responses was markedly higher for the SCEPT than for the standard AMT. Also, overgeneral responding on the SCEPT was positively associated to depression scores and depressive rumination scores, whereas overgeneral responding on the AMT was not. Results suggest that the SCEPT, relative to the AMT, is a more sensitive instrument to measure OGM, at least in non-clinical populations. Study 2 further showed that this enhanced sensitivity is most likely due to the omission of the instruction to be specific rather than to the SCEPT's sentence completion format (as opposed to free recall to cue words).     

Significant other primes and behavior: motivation to respond to social cues moderates pursuit of prime-induced goals

Significant others can automatically activate a variety of goals, including goals that significant others have for an individual and the individual's personal goals that are associated with the significant others. Across three studies, this article shows that the effects of significant other primes (i.e., mother, roommate) on behavior depend on individual differences in both personal goals and responsiveness to social cues (i.e., self-monitoring, need to belong). Specifically, individuals who are motivated to respond to social cues assimilate to a goal that their primed significant other has for them, regardless of whether they personally hold the goal. Individuals not so motivated, on the other hand, assimilate to the goal only when it is one that they also personally hold. Implications of these findings for research on the prime-to-behavior relationship and interpersonal goal pursuit are discussed.
