The Poggendorff illusion: premeditated or unpremeditated misbehaviour?

Poggendorff illusions have sometimes been explained as arising in a two-stage process, with misalignment consequent upon prior, independently observable misjudgments of angle, extent, or proportion. However, several misalignments combined in one figure can be arranged so that if such prior illusions were the cause, they would have to transform simultaneously in opposed directions to save appearances. When Poggendorff misalignments are deliberately embedded in other illusions, results are intriguingly various, but the comparison of Poggendorff figures with and without associated illusions suggests that the underlying misalignments arise from pre-attentive cues, local to each traverse across a gap.     

Covariates of production and perseveration on tests of phonemic, semantic and alternating fluency in normal aging

Standard measures of phonemic and semantic fluency, as well as fluency measures that impose additional demands upon set-switching were administered to younger and older adults. No age effect was found for total output on semantic fluency, while older participants generated significantly more responses relative to their younger counterparts on the phonemic measure. However, older adults made significantly more perseverative errors on both these measures. For tests of alternating fluency, only where participants were required to switch between two semantic dimensions, was an age deficit observed. Although the correlation between phonemic repetitions and age remained significant when performance on the Digit Symbol Test or a measure of fluid intelligence was partialled out, age effects for semantic repetitions and semantic alternating fluency were substantially reduced. The age benefit for number of correct responses upon phonemic fluency was significantly attenuated when a measure of crystallized intelligence was entered as a control variable. The theoretical and practical implications of these results are discussed.     

The relation between auditory temporal interval processing and sequential stream segregation examined with stimulus laterality differences

In this study, we examine the effects of laterality differences between noise bursts on two objective measures of temporal interval processing (gap detection and temporal asymmetry detection) and one subjective measure of temporal organization (stream segregation). Noise bursts were lateralized by presentation to different ears or dichotic presentation with oppositely signed interaural level (ILD) or time (ITD) differences. Objective thresholds were strongly affected by ear-of-entry differences, were moderately affected by ILD differences, but were unaffected by ITD differences. Subjectively, A and B streams segregated well on the basis of ear-of-entry or ILD differences but segregated poorly on the basis of ITD differences. These results suggest that perceptual segregation may be driven more effectively by differential activation of the two ears (peripheral channeling) than by differences in perceived laterality.     

Infants' ability to connect gaze and emotional expression to intentional action

Four studies investigated whether and when infants connect information about an actor's affect and perception to their action. Arguably, this may be a crucial way in which infants come to recognize the intentional behaviors of others. In Study 1 an actor grasped one of two objects in a situation where cues from the actor's gaze and expression could serve to determine which object would be grasped, specifically the actor first looked at and emoted positively about one object but not the other. Twelve-month-olds, but not 8-month-olds, recognized that the actor was likely to grasp the object which she had visually regarded with positive affect. Studies 2, 3, and 4 replicated the main finding from Study 1 with 12- and 14-month-olds and included several contrasting conditions and controls. These studies provide evidence that the ability to use information about an adult's direction of gaze and emotional expression to predict action is both present, and developing at the end of the first year of life.     

Structure of preschool phonological sensitivity: overlapping sensitivity to rhyme,words, syllables,and phonemes

Phonological sensitivity is an important causal variable in reading acquisition; however, there is controversy concerning its nature. One view holds that sensitivity to various linguistic units reflects independent abilities, whereas another holds sensitivity to these units reflects one ability. We examined relations among sensitivity to words, syllables, rhymes, and phonemes in 149 older preschool children (4- and 5-year-olds) and 109 younger preschool children (2- and 3-year-olds) who completed eight measures of phonological sensitivity and measures of print knowledge. Confirmatory factor analyses of all combinations of word, syllable, rhyme, and phoneme factors found that a one-factor model best explained the data from both groups of children (CFIs >.98). Only variance common to all phonological sensitivity skills was related to print knowledge and rudimentary decoding. Findings support a developmental conceptualization of phonological sensitivity.     

Do people aggress to improve their mood? Catharsis beliefs, affect regulation opportunity, and aggressive responding

Do people aggress to make themselves feel better? We adapted a procedure used by G. K. Manucia, D. J. Baumann, and R. B. Cialdini (1984), in which some participants are given a bogus mood-freezing pill that makes affect regulation efforts ineffective. In Study 1, people who had been induced to believe in the value of catharsis and venting anger responded more aggressively than did control participants to insulting criticism, but this aggression was eliminated by the mood-freezing pill. Study 2 showed similar results among people with high anger-out (i.e., expressing and venting anger) tendencies. Studies 3 and 4 provided questionnaire data consistent with these interpretations, and Study 5 replicated the findings of Studies 1 and 2 using measures more directly concerned with affect regulation. Taken together, these results suggest that many people may engage in aggression to regulate (improve) their own affective states.     

The role of decision influence and team performance in member self-efficacy, withdrawal, satisfaction with the leader, and willingness to return

This study examines team performance as a moderator of the relationship between decision influence and outcomes relevant to team effectiveness in hierarchical teams with distributed ex pertise. In this type of team staff members have unique roles and make recommendations to the team leader, who ultimately makes the team's final decisions. It is suggested that the positive rela tionship between decision influence and favorable outcomes (e.g., satisfaction) consistently described in the literature is dependent on team performance in this type of team. Specifically, team effec tiveness outcomes are proposed to be consistently more favorable in higher performing than in lower performing teams. Decision influence is proposed to relate positively to member satisfaction with the leader, willingness to return, and self-efficacy and to relate negatively to withdrawal in higher performing teams. The opposite pattern of relationships is expected in lower performing teams. A laboratory study was conducted with 228 undergradu ates performing a computer task as subordinates in 76 four-person teams with a confederate leader. The results generally support the hypotheses and illustrate a dilemma for leaders attempting to manage team effectiveness.     

Exploring own-age biases in deception detection

The present study explored own-age biases in deception detection, investigating whether individuals were more likely to trust those in their own-age group. Younger and older participants were asked to detect deceit from videos of younger and older speakers, rating their confidence in each decision. Older participants showed an own-age bias: they were more likely to think that deceptive speakers of their own age, relative to younger speakers, were telling the truth. Older participants were also more confident in their judgements of own-age, relative to other-age, speakers. There were no own-age biases for younger participants. In a subsequent (apparently unrelated) task, participants were asked to rate the trustworthiness of the speakers. Both age groups of participants trusted younger speakers who had previously told the truth more compared to those who had lied. This effect was not found for older speakers. These findings are considered in relation to the in-group/out-group model of social cognition and common stereotypical beliefs held about younger and older adults.     

Parental Influence on Children during Educational Television Viewing in Immigrant Families

It has been suggested by researchers that educational television programmes may support the language and literacy development for children, especially those in immigrant families. In an immigrant family, many family characteristics appear to be related to educational television programme viewing of children at home, for example, parental acculturation (the process of adapting to the new culture) and parental mediation (supervision and guidance) of television viewing. In the present work, the parental influence on children during educational television viewing was studied quantitatively, based on a sample (n = 171) of immigrant families with children aged 3–6 years collected across the U.S. The results have revealed that significant differences existed between Asian and Hispanic groups in coviewing mediation and in their children's educational television viewing. Furthermore, language in parental acculturation significantly predicted instructive and restrictive parental mediation, and parental occupation significantly predicted language in parental acculturation. This study initiates the attention to the topic of educational television viewing in immigrant families, which warrants further investigations in the future as the Asian and Hispanic immigrant population increases rapidly in the U.S. Copyright © 2013 John Wiley & Sons, Ltd.     

Studies of Rorschach Content; A Review of Research Literature Part II; Non-Traditional Uses of Content Indicators

This paper deals with the extension of research on Rorschach content to new modes of scoring and classifying test reponses that lie outside of the conventional classification scheme. Four avenues of going beyond the traditional content categories are presented and reviewed: study of subdivisions within the units of the generally used scoring system, exploration of the symbolic meaning of Rorschach responses, investigation of constellations of content signs, and development and validation of content scales. Little systematic work has been done in the first two areas of endeavor. As far as the latter two research topics are concerned, the evidence accumulated suggests that, at best, scales and signs derived from content yield overlap, and not correspondence, with their respective real-life referents. The study of mediating variables that act to magnify or reduce the extent of this relationship has merely begun and remains the major unfulfilled task in Rorschach content research.
