Attentional episodes in visual perception

Is one's temporal perception of the world truly as seamless as it appears? This article presents a computationally motivated theory suggesting that visual attention samples information from temporal episodes (episodic simultaneous type/serial token model; Wyble, Bowman, & Nieuwenstein, 2009). Breaks between these episodes are punctuated by periods of suppressed attention, better known as the attentional blink (Raymond, Shapiro, & Arnell, 1992). We test predictions from this model and demonstrate that participants were able to report more letters from a sequence of 4 targets presented in a dense temporal cluster than from a sequence of 4 targets interleaved with nontargets. However, this superior report accuracy comes at a cost in impaired temporal order perception. Further experiments explore the dynamics of multiple episodes and the boundary conditions that trigger episodic breaks. Finally, we contrast the importance of attentional control, limited resources, and memory capacity constructs in the model.     

Sweets,Sex, or Self‐Esteem? Comparing the Value of Self‐Esteem Boosts With Other Pleasant Rewards

Abstract Many people ascribe great value to self‐esteem, but how much value? Do people value self‐esteem more than other pleasant activities, such as eating sweets and having sex? Two studies of college students ( Study 1 : N=130; Study 2 : N=152) showed that people valued boosts to their self‐esteem more than they valued eating a favorite food and engaging in a favorite sexual activity. Study 2 also showed that people valued self‐esteem more than they valued drinking alcohol, receiving a paycheck, and seeing a best friend. Both studies found that people who highly valued self‐esteem engaged in laboratory tasks to boost their self‐esteem. Finally, personality variables interacted with these value ratings. Entitled people thought they were more deserving of all pleasant rewards, even though they did not like them all that much (both studies), and people who highly value self‐esteem pursued potentially maladaptive self‐image goals, presumably to elevate their self‐esteem ( Study 2 ).     

A Psychometric Analysis of the Revised Child Anxiety and Depression Scales—Parent Version in a School Sample

The Revised Child Anxiety and Depression Scale—Parent Version (RCADS-P) is a parent-report questionnaire of youth anxiety and depression with scales corresponding to the DSM diagnoses of separation anxiety disorder, social phobia, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, and major depressive disorder. The RCADS-P was recently developed and has previously demonstrated strong psychometric properties in a clinic-referred sample (Ebesutani et al., Journal of Abnormal Child Psychology 38, 249–260, 2010b). The present study examined the psychometric properties of the RCADS-P in a school-based population. As completed by parents of 967 children and adolescents, the RCADS-P demonstrated high internal consistency, test-retest reliability, and good convergent/divergent validity, supporting the RCADS-P as a measure of internalizing problems specific to depression and five anxiety disorders in school samples. Normative data are also reported to allow for the derivation of T-scores to enhance clinicians’ ability to make classification decisions using RCADS-P subscale scores.     

Attention blinks for selection, not perception or memory: reading sentences and reporting targets

In whole report, a sentence presented sequentially at the rate of about 10 words/s can be recalled accurately, whereas if the task is to report only two target words (e.g., red words), the second target suffers an attentional blink if it appears shortly after the first target. If these two tasks are carried out simultaneously, is there an attentional blink, and does it affect both tasks? Here, sentence report was combined with report of two target words (Experiments 1 and 2) or two inserted target digits, Arabic numerals or word digits (Experiments 3 and 4). When participants reported only the targets an attentional blink was always observed. When they reported both the sentence and targets, sentence report was quite accurate but there was an attentional blink in picking out the targets when they were part of the sentence. When targets were extra digits inserted in the sentence there was no blink when viewers also reported the sentence. These results challenge some theories of the attentional blink: Blinks result from online selection, not perception or memory.     

Explaining the paradoxical rejection-aggression link: the mediating effects of hostile intent attributions, anger, and decreases in state self-esteem on peer rejection-induced aggression in youth

People are strongly motivated to feel accepted by others. Yet when faced with acute peer rejection they often aggress against the very peers they desire acceptance from, which may lead to further rejection. The present experiment tests three potential mediators of aggressive responses to acute peer rejection in the critical developmental stage of early adolescence. Participants (N=185, M(age)=11.5 years) completed personal profiles that were allegedly evaluated online by peers. After receiving negative or neutral peer feedback, participants could aggress against the same peers who had evaluated them. Rejected participants attributed more hostile intent to the peers, were angrier, showed a greater reduction in state self-esteem, and were more aggressive. Mediational analyses showed that hostile intent attributions mediated the acute peer rejection-aggression relationship, whereas increases in anger and decreases in state self-esteem did not. Thus, acute peer rejection evokes hostile intent attributions that, in turn, lead to aggressive reactions.     

Figural vividness and persuasion: capturing the "elusive" vividness effect

Despite the widespread belief that the use of vividness in persuasive communications is effective, many laboratory studies have failed to find vividness effects. A possible explanation for this discrepancy is that many laboratory tests have not vivified solely the central thesis of the message but have vivified irrelevant portions of the message as well or instead. Two experiments examined the effect of vivifying the central ("figure") or noncentral ("ground") features of a message on persuasion. In both experiments, the formerly "elusive vividness effect" of superior persuasion was found, but only in vivid-figure communications. A mediation analysis revealed the salutary role of supportive cognitive elaborations, rather than memory for the communication, in mediating the vividness effect. The findings caution against attempts to persuade by increasing overall message vividness because off-thesis vividness has the unintended and undercutting consequence of distracting recipients from the point of the communication.     

QUASI‐NATURALISM AND MORAL REALITY

In his recent book Moral Reality, Paul Bloomfield has put forward an original set of arguments for moral realism. Central to his treatment is an argument for the reality of moral properties, one which models them on the property of being healthy. The paper is a critical examination of Bloomfield's central line of argument. It is contended that his proposed method of grounding moral realism fails, inasmuch as his Distinction Test criterion for property reality – essentially the claim that a property exists if its existence is required for distinctions that we make and must make – is inadequate. An alternative approach toward properties is suggested, which has the result, inter alia, that Bloomfield's quasi‐naturalistic approach is unnecessary for the defense of moral realism.¹     

Accusers Lie and Other Myths: Rape Myth Acceptance Predicts Judgments Made About Accusers and Accused Perpetrators in a Rape Case

Previous research results have yielded a consistent link between rape myth acceptance and sexual assault victim blaming: Individuals reporting higher levels of rape myth acceptance also report higher levels of victim blaming. In four studies we explored whether the presentation of rape-myth confirming information or rape-myth debunking information might moderate these tendencies. In these studies, U.S. undergraduates (97 in Study 1, 84 in Study 2, 98 in Study 3, and 116 in Study 4) read scenarios of a heterosexual sexual assault case and were randomly assigned to a control condition, a rape myth confirmation condition, or a rape myth debunking condition; they also reported the extent to which they endorsed or accepted rape myths. Rape myth acceptance robustly correlated with judgments made about accusers and accused rapists regardless whether the accuser/accused pairing was female/male (Studies 1 and 2) or male/female (Studies 3 and 4). For example, those who most strongly endorsed rape myths were also likely to disbelieve accusers. There were few instances indicating that the presentation of rape myth confirming information or rape myth debunking information moderated these effects. This lack of moderation occurred regardless of whether the information came from trial lawyers or from expert witnesses in the case. The relative impotence of the information presentations could be due to several factors (e.g., entrenched nature of rape myth acceptance, psychological reactance, timing and strength of manipulation), and we suggest ideas for how to overcome this relative impotence in future research.
