A Below‐Average Effect with Respect to American Political Stereotypes on Warmth and Competence

The “above‐average effect” is the phenomenon that people tend to judge themselves above average on desirable traits. Based on social identity theory, we propose that a “below‐average effect” may arise when individuals rate themselves and the average ingroup member on traits stereotypically associated with the ingroup. In two studies, Republican and Democrat participants rated themselves and the average political ingroup member on possession of desirable traits related to warmth and competence. Current political stereotypes in America associate the former dimension with Democrats and the latter with Republicans. Consistent with our hypothesis, the above‐average effect was moderated by political group and dimension in interaction. In particular, Democrats rated themselves below the average Democrat on warmth and Republicans rated themselves below the average Republican on competence.     

The Wished‐For Always Wins Until the Winner Was Inevitable All Along: Motivated Reasoning and Belief Bias Regulate Emotion During Elections

How do biases affect political information processing? A variant of the Wason selection task, which tests for confirmation bias, was used to characterize how the dynamics of the recent U.S. presidential election affected how people reasoned about political information. Participants were asked to evaluate pundit‐style conditional claims like “The incumbent always wins in a year when unemployment drops” either immediately before or immediately after the 2012 presidential election. A three‐way interaction between ideology, predicted winner (whether the proposition predicted that Obama or Romney would win), and the time of test indicated complex effects of bias on reasoning. Before the election, there was partial evidence of motivated reasoning—liberals performed especially well at looking for falsifying information when the pundit's claim predicted Romney would win. After the election, once the outcome was known, there was evidence of a belief bias—people sought to falsify claims that were inconsistent with the real‐world outcome rather than their ideology. These results suggest that people seek to implicitly regulate emotion when reasoning about political predictions. Before elections, people like to think their preferred candidate will win. After elections, people like to think the winner was inevitable all along.     

Normative and idiosyncratic measures of positive and negative affect in sport

Objectives: The purposes of the study were to: (a) ascertain the degree of similarity amongst normative and idiosyncratic measures of affect; (b) test the notion of reversal effects on the functional impact and the hedonic tone of emotions; (c) analyse the differences on the intensity of facilitating-positive, facilitating-negative, inhibiting-positive, and inhibiting-negative performance emotion content categories, and (d) test whether competitive trait anxiety intensity could predict pre-performance normative or idiosyncratic negative affect intensity.Design: A cross-sectional study design was employed using normative and idiosyncratic measures of affect.Methods: Experienced male soccer and volleyball players (N =124) were individually assessed. Normative scales were the Positive and Negative Affect Schedule (PANAS) used as a sport-specific trait measure of competitive affect, and the Sport Anxiety Scale (SAS) administered for the assessment of competitive trait anxiety. Idiosyncratic affect occurring prior to or during optimal and poor competitions was identified in the conceptual framework of the Hanin's Individual Zones of Optimal Functioning (IZOF) model (Hanin, Y.L. (1997). Emotions and athletic performance: Individual zones of optimal functioning model. European Yearbook of Sport Psychology, 1, 29–72).Results: Findings revealed low overlap amongst the PANAS items and the idiosyncratic items, reversal effects on the functional impact and the hedonic tone of emotions, higher level of positive affect associated with optimal performance when compared with all other affect categories, and lower levels of facilitating-negative category when compared with the facilitating-positive. Moreover, sport trait anxiety intensity was found to predict negative affect intensity as assessed by the PANAS normative scales and by the idiosyncratic items. For idiosyncratic affect, however, significant differences emerged only when comparing individuals with very high or very low anxiety symptoms.Conclusions: Idiosyncratic affect scales together with normative scales are recommended for research and applied purposes. The functional impact as well as the hedonic tone of emotion items need to be examined according to individual perception.     

On the discriminability of stimulus duration.

The performance of pigeons trained to detect differences in the duration of stimuli was analysed using a matching model of signal detection. Two white stimuli, S1 and S2, differing in duration, were arranged with equal probability on the center key of a three-key chamber. S1 was systematically varied from 5 seconds to 25 seconds while S2 remained constant at 30 seconds. On completion of the center-key stimulus, a peck on the center key turned on the two red side keys. A left-key response was "correct" when S1 had been in effect on the center key and a right-key response was "correct" on S2 trials. A correct response produced a 3-second magazine light accompanied intermittently by food. Incorrect responses produced 3-second blackouts. Detection performance was measured under two procedures. In the first, the obtained reinforcement ratio was uncontrolled by allowing the number of food reinforcements obtained for correct left- and right-key responses to vary as the stimuli were changed. In the second procedure, the presentation of food reinforcement was controlled by holding the obtained reinforcement ratio constant. Discriminability changed as a function of stimulus differences under both procedures. No such trend was found in response bias.     

The interaction of stimulus and reinforcer control in complex temporal discrimination.

Six pigeons were trained in a discrete-trials signal-detection procedure to discriminate between a fixed-duration stimulus (5 s or 20 s) and a set of variable durations ranging from 2.5 s to 57.5 s in steps of 5 s. For each fixed-duration stimulus, the ratio of reinforcer frequencies contingent upon reporting the fixed versus the variable stimulus was systematically manipulated. Detection performance was well controlled by both the stimulus value and the reinforcer ratio. Both the discriminability between the fixed duration and the set of variable durations, and the discriminability between the fixed duration and each of the variable durations, were independent of the reinforcer-frequency ratio when discriminability was measured as log d. The sensitivity of response bias to reinforcement-ratio changes was independent of the value of the fixed duration, but was not independent of the discriminability of the variable durations from the fixed durations. Under current models, discriminability measures in complex temporal discrimination may be independent of biasing manipulations, but bias measures are not independent of stimulus values.     

EFFECTS OF WITHIN-STIMULUS AND EXTRA-STIMULUS PROMPTING ON DISCRIMINATION LEARNING IN AUTISTIC CHILDREN1

Two different prompting procedures to teach visual and auditory discriminations to autistic children were compared. The first involved presenting an added cue as an extra-stimulus prompt. This required the child to respond to both prompt and training stimulus. The second involved the use of a within-stimulus prompt. This consisted of an exaggeration of the relevant component of the training stimulus and thus did not require that the child respond to multiple cues. The results indicated that (1) children usually failed to learn the discriminations without a prompt, (2) children always failed to learn when the extra-stimulus prompt was employed but usually did learn with the withinstimulus prompt, and (3) these findings were independent of which modality (auditory or visual) was required for the discrimination.     

The effects of different component response requirements in multiple and concurrent schedules

Six pigeons were trained on multiple and concurrent schedules. The reinforcement rates were varied systematically (a) when lever pressing was required in one component and key pecking in the successive component; (b) when lever pressing was required in both multiple components; (c) when key pecking was required in both multiple components; and (d) when key pecking was required on one schedule and lever pressing was required on the concurrently-available schedule. Only the absolute level of responding was changed by different response requirements. Analyzed by the generalized matching law, performance under different response requirements resulted in a bias toward key pecking, and the measured response bias was the same in multiple and concurrent schedule arrangements. The bias in time measures obtained from concurrent schedule performance was reliably smaller than the obtained response biases. The sensitivity to reinforcement-rate changes was ordered: concurrent key-lever; multiple key-key; multiple lever-key; and, the least sensitive, multiple lever-lever. The results confirm that requirements of different topographical responses can be handled by the generalized matching law mainly in the bias parameter, but problems for this type of analysis may be caused by the changing sensitivity to reinforcement in multiple schedule performance as response requirements are changed.     

Trait anxiety, defensiveness and selective processing of threat: an investigation using two measures of attentional bias

Attentional biases for threat were examined in a non-clinical sample (N=60), with each participant tested on both the modified Stroop colour-naming and dot probe tasks. Three groups were selected on the basis of trait anxiety and social desirability scale (SDS) scores: “low anxiety” (LA: low trait, low SDS), “repressor” (REP: low trait, high SDS) and “high anxiety” (HA: high trait, low SDS). Results from the colour-naming task suggested that high levels of defensiveness (in combination with low trait anxiety) were associated with greater avoidance of threat. The REP group showed less interference in colour-naming threat than neutral words; whereas the HA group showed increased interference due to threat words. On the dot probe task, there was a general tendency for this non-clinical sample as a whole to show avoidance of social threat relative to neutral words, but there was no bias for physical threat words. Avoidance of social threat was significant only within the REP group. No relationships were found between the measures of cognitive bias from the two tasks, suggesting different underlying mechanisms. Results are discussed in relation to previous findings and theoretical views of the effects of anxiety and defensiveness on the processing of threat.     

Moderating Effects of Mothers' Attribution on the Relationships Between Their Affect and Parenting Behaviors and Children's Aggressive Behaviors

We examined Bugental's (1987) transactional model in the context of the relationships between aggressive children and their mothers. Based on Bugental's model, it was hypothesized that mothers who possessed the attributional style of low self-control and high child-control over hypothetical child care failure were more likely to manifest negative affect and negative parenting behaviors toward their child, only when their child is aggressive. Children's aggressive behavior was assessed via mothers' and teachers' ratings. Sixty-six children and their mothers served as subjects. Our results provided support for mothers' negative affect when using teachers' rating of children's aggressive behaviors only. Possible explanations for the differential results obtained using mothers' and teachers' ratings of children's aggressive behaviors were discussed.     

Criteria Based Content Analysis: The Less Scientific Road to Truth

Criteria Based Content Analysis (CBCA) is a forensic tool that aims atdistinguishing true from false statements made by crime victims. As such,CBCA and similar techniques are regularly employed by psychologicalexpert-witnesses in court. However, it could be argued that the diagnosticaccuracy of CBCA is moderate, and too low for application in the forensiccontext. The current article discusses problems that arise if conclusionsabout credibility of testimonies based on CBCA are presented in court. Afundamental, yet so far hardly addressed flaw is that CBCA suffers from aninherent truth bias. That is, the underlying notion that credibility isexamined by means of searching for signs supporting truthfulness isscientifically less valid than the approach in which credibility isestablished by focusing on alternative explanations and signs of deceit.
