Out of sight,out of mind: The attentional blink can eliminate synaesthetic colours

Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were embedded an oriented grating (T1) and a letter-prime (T2), forming a modified attentional blink (AB) task. At the end of the stream a coloured probe appeared that was either congruent or incongruent with the synaesthetic colour elicited by the letter-prime. When the prime was attended, synaesthetes showed a reliable effect of prime-probe congruency. In contrast, when the prime appeared at 350 ms following T1 (during the AB), the congruency effect was eliminated. Our findings suggest that focused attention is crucial for inducing letters to elicit colours in synaesthesia.     

Planning in sentence production: Evidence for the phrase as a default planning scope

Controversy remains as to the scope of advanced planning in language production. Smith and Wheeldon (1999) found significantly longer onset latencies when subjects described moving-picture displays by producing sentences beginning with a complex noun phrase than for matched sentences beginning with a simple noun phrase. While these findings are consistent with a phrasal scope of planning, they might also be explained on the basis of: (1) greater retrieval fluency for the second content word in the simple initial noun phrase sentences and (2) visual grouping factors. In Experiments 1 and 2, retrieval fluency for the second content word was equated for the complex and simple initial noun phrase conditions. Experiments 3 and 4 addressed the visual grouping hypothesis by using stationary displays and by comparing onset latencies for the same display for sentence and list productions. Longer onset latencies for the sentences beginning with a complex noun phrase were obtained in all experiments, supporting the phrasal scope of planning hypothesis. The results indicate that in speech, as in other motor production domains, planning occurs beyond the minimal production unit.     

A review of recent studies on differential reinforcement during skill acquisition in early intervention

Although the use of differential reinforcement has been recommended in previous investigations and in early intervention curriculum manuals, few studies have evaluated the best method for providing differential reinforcement to maximize independent responding. This paper reviews previous research on the effectiveness of differential reinforcement as treatment and describes important areas of future research.     

Who Cares? The Role of Job Involvement in Psychological Contract Violation

This study examined survey data from full‐time employees employed in a variety of occupations. We empirically examined how psychological involvement with one's job affects reactions to psychological contract violation. Data for control variables (i.e., age, gender, organizational tenure), the independent variable (i.e., psychological contract violation), and the moderator (i.e., job involvement) were taken at Time 1; and dependent variables (i.e., depressed mood at work, turnover intention) were taken at Time 2. Results illustrated that job involvement was an important construct in understanding individuals' negative reactions to psychological contract violations. Implications and limitations are discussed, and suggestions for future research are offered.     

Mating competitors increase religious beliefs

It has been presumed that religiosity has an influence on mating behavior, but here we experimentally investigate the possibility that mating behavior might also influence religiosity. In Experiment 1, people reported higher religiosity after looking at mating pools consisting of attractive people of their own sex compared to attractive opposite sex targets. Experiment 2 replicated the effect with an added control group, and suggested that both men and women become more religious when seeing same-sex competitors. We discuss several possible explanations for these effects. Most broadly, the findings contribute to an emerging literature on how cultural phenomena such as religiosity respond to ecological cues in potentially functional ways.     

Event-related brain potentials and cognitive processes related to perceptual—motor information transmission

In the present study, event-related potentials (ERPs) were recorded to investigate cognitive processes related to the partial transmission of information from stimulus recognition to response preparation. Participants classified two-dimensional visual stimuli with dimensions size and form. One feature combination was designated as the go-target, whereas the other three feature combinations served as no-go distractors. Size discriminability was manipulated across three experimental conditions. N2c and P3a amplitudes were enhanced in response to those distractors that shared the feature from the faster dimension with the target. Moreover, N2c and P3a amplitudes showed a crossover effect: Size distractors evoked more pronounced ERPs under high size discriminability, but form distractors elicited enhanced ERPs under low size discriminability. These results suggest that partial perceptual—motor transmission of information is accompanied by acts of cognitive control and by shifts of attention between the sources of conflicting information. Selection negativity findings imply adaptive allocation of visual feature-based attention across the two stimulus dimensions.     

Understanding Adolescent Substance Abuse: Prevalence,Risk Factors,and Clinical Implications

From a developmental perspective, adolescence is a time of gaining independence, experimentation, and taking risks. One area of experimentation associated with adolescence is substance use. For counselors working with adolescents who use or abuse substances, or both, it is important to understand the scope of the problem and ways to effectively work with this population. This article provides counselors with current information on adolescent substance abuse and suggestions for clinical work.     

The Effect of Employee Trust of the Supervisor on Enterprising Behavior: A Cross-Cultural Comparison

This study examines the effects of an employee’s affect-based and cognition-based trust of the supervisor on that employee’s enterprising behavior. The extent to which two cultural dimensions, power distance and in-group collectivism, moderate the relationship between the trust measures and enterprising behavior is considered. Trust ratings were provided by 130 U.S. employees, 202 Turkish employees, 101 Polish employees, and 86 Russian employees. Their 519 supervisors then provided ratings of those employees’ enterprising behavior. The results show that both affect-based trust and cognition-based trust have a significant, but modest, effect on the employee’s enterprising behavior. Our findings indicate that both power distance and in-group collectivism do not moderate the proposed trust-behavior relationship although power distance almost reaches the level of significance. We call for further research on other moderating variables to explain the findings.     

Is Incompatibilism Intuitive?

Incompatibilists believe free will is impossible if determinism is true, and they often claim that this view is supported by ordinary intuitions. We challenge the claim that incompatibilism is intuitive to most laypersons and discuss the significance of this challenge to the free will debate. After explaining why incompatibilists should want their view to accord with pretheoretical intuitions, we suggest that determining whether incompatibilism is in fact intuitive calls for empirical testing. We then present the results of our studies, which put significant pressure on the claim that incompatibilism is intuitive. Finally, we consider and respond to several potential objections to our approach.
