Flank transparency: transparent filters seen in dynamic two-color displays

Flank transparency is the perception of a colored transparent filter evoked by apparent-motion displays containing as few as two colors. Displays of flank transparency contain a random array of line segments placed on a uniform background. Small flanks are added to the line segments if the segments fall in the interior of a moving virtual shape, such as a virtual disk. This leads to the perception of a colored transparent disk with well-defined boundaries moving over the array of lines. Current qualitative and quantitative models of luminance and color conditions for perceptual transparency do not account for flank transparency as they require displays containing at least three different colors.     

Why interleaving enhances inductive learning: The roles of discrimination and retrieval

Kornell and Bjork (Psychological Science 19:585–592, 2008) found that interleaving exemplars of different categories enhanced inductive learning of the concepts based on those exemplars. They hypothesized that the benefit of mixing exemplars from different categories is that doing so highlights differences between the categories. Kang and Pashler (Applied Cognitive Psychology 26:97–103, 2012) obtained results consistent with this discriminative-contrast hypothesis: Interleaving enhanced inductive learning, but temporal spacing, which does not highlight category differences, did not. We further tested the discriminative-contrast hypothesis by examining the effects of interleaving and spacing, as well as their combined effects. In three experiments, using photographs of butterflies and birds as the stimuli, temporal spacing was harmful when it interrupted the juxtaposition of interleaved categories, even when total spacing was held constant, supporting the discriminative-contrast hypothesis. Temporal spacing also had value, however, when it did not interrupt discrimination processing.     

Maternal Role Confusion: Relations to Maternal Attachment and Mother–Child Interaction from Infancy to Adolescence

Self‐reports of role confusion with the parent in childhood are associated with a variety of adverse outcomes. However, role‐confusion has been studied primarily from the point of view of the child. The current study evaluated an instrument for assessing role confusion from maternal interviews rather than from child observations or self‐reports in adulthood. Fifty‐one mothers participating in a longitudinal study since their own child's infancy were administered the Experiences of Caregiving Interview (C. George & J. Solomon, 1996) when the child was age 20. Interviews were coded using the newly developed Parental Assessment of Role Confusion (PARC; L. Vulliez‐Coady & K. Lyons‐Ruth, 2009). Maternal PARC scores were related to observational measures of role‐confusion in interaction with the child both in infancy and late adolescence. PARC scores also were related to mothers’ hostile‐helpless states of mind on the Adult Attachment Interview (C. George, N. Kaplan, & M. Main, 1984, 1985, 1986) and to the extent of Unresolved loss, but not Unresolved Trauma. PARC scores also were related to mothers’ self‐reports of helplessness experienced in the parenting role. Discriminant validity of the PARC was demonstrated in that role confusion on the PARC was not related to hostile or disoriented forms of parent–child interaction. Implications for clinical assessment of role confusion are discussed.     

The role of honour concerns in emotional reactions to offences

We investigated the role of honour concerns in mediating the effect of nationality and gender on the reported intensity of anger and shame in reaction to insult vignettes. Spain, an honour culture, and The Netherlands, where honour is of less central significance, were selected for comparison. A total of 260 (125 Dutch, 135 Spanish) persons participated in the research. Participants completed a measure of honour concerns and answered questions about emotional reactions of anger and shame to vignettes depicting insults in which type of threat was manipulated. It was found that Spanish participants responded especially intensely to insults that threaten family honour, and that this effect of nationality on emotional reactions to threats to family honour was mediated by individual differences in concern for family honour.     

Male and Female Voices in Commercials: Analysis of Effectiveness, Adequacy for the Product, Attention and Recall

In radio advertising, there is a strong tendency to employ male voices more often than female voices in the belief that male voices sound more convincing. As a result, a gender stereotype is established which would appear to be upheld more by tradition than actual advertising effectiveness. This experimental study analyses the influence of gender on the effectiveness of the voice in terms of adequacy to the product, the ability to attract listeners’ attention and the degree to which voice gender contributes to recall. The objective is to ascertain whether or not the patent infra-use of the female voice is justified. To this end, a gender-balanced sample of 372 students of journalism from Spain was employed. The findings show that when a question is asked about an alleged association with a pre-existing vocal stereotype the answer is consistent with the gender of the voice and the type of product, though this does not occur when the aspects are unrelated, such as voice effectiveness, attention or recall. Accordingly, the supremacy of the male voice over the female voice in radio advertising and the repeated association between voices and types of products is more based on tradition than on alleged advertising effectiveness.     

Prenatal Genetic Testing: An Investigation of Determining Factors Affecting the Decision-Making Process

Despite the increase in popularity of prenatal genetic testing, relatively little is known about the role psychological factors play in the decision-making process. In this analogue study, a sample of Italian female university students was used to investigate determining factors that predict the intention of undergoing prenatal genetic testing. Structural Equation Modelling was used to describe the dynamic interplay between knowledge, beliefs, attitudes and health-related behaviour such as prenatal genetic testing. Following the Theory of Reasoned Action, three dimensions predicted the intention to undergo prenatal genetic testing: the need for more scientific information, a positive attitude towards genetic testing, and the inclination to terminate pregnancy after receiving a positive test result. Results showed that less religious women tended to be more in favour of prenatal tests and in undertaking such tests. This preliminary study provides genetic counsellors and policy makers with a clearer picture of their clients’ motives and attitudes behind the decision-making process of prenatal genetic testing, contributing to improving both the communication process between counsellors and their clients and the organization of genetic services.     

The Effect of Suspense on Enjoyment Following a Desirable Outcome: The Mediating Role of Relief

Although endemic to many forms of media entertainment, suspense represents a paradox for enjoyment because it is experienced as an aversive state. Three studies are presented across two media contexts demonstrating how outcomes to suspenseful episodes affect viewers' relief. Study 1 shows that relief is elicited only when a film's outcome is unambiguously favorable and under such conditions is positively related to enjoyment. No such relationship was found given an ambiguous outcome. Study 1 provides evidence that relief is distinct from other affective responses (i.e., positive and negative affect, surprise) that may be present following suspense. Studies 2 and 3 use competitive contests as a context and provide evidence that relief mediates the effect of suspense on enjoyment. Study 2 shows that the previously positive effects of suspense and expectation disconfirmation on enjoyment are obviated in the presence of relief. Study 3 varies suspense in real time across 14 simulated races. Also manipulated are affective dispositions toward the racers and race outcome. The results reveal that relief mediates the effect of suspense on enjoyment, but only when the outcome favors a preferred competitor. The research enhances our understanding of the intertwining of cognition and affect in the enjoyment of suspense.     

Considering spatial ability in virtual route learning in early aging

The aim of this study is to broaden our understanding of the construction and early decline of spatial mental representations in route learning, considering the extent to which spatial ability and age-related differences in environment learning interact. The experiment examines spatial mental representation derived from taking a realistic route acquired using virtual environment and compares individuals different in age but with similar spatial ability. A sample of 34 young (20–30 years) and 30 middle-aged (50–60 years) females with good mental rotation ability were chosen. Participants learned a complex route through its presentation in a virtual environment and then performed a series of tasks (landmark recognition, location of landmarks and verification of spatial relations). Results show that the two participant age groups had similar performance in landmark recognition task and in verification of sentences describing direct spatial relations; instead, the middle-aged group showed a poorer performance than younger in their ability to locate landmarks and to judge the truth of indirect spatial sentences. These results first suggest that spatial abilities have to be seriously considered to avoid any confusion with age, as age-related differences are attenuated when individuals are different in age but similar in spatial ability. Second they confirm a specific difficulty of older participants to handle spatial information in a global configuration.     

Parenting stress and external stressors as predictors of maternal ratings of child adjustment

This study sought to disentangle the effects of different kinds of stress on maternal ratings of child externalizing and internalizing problems, social inhibition, and social competence, with a primary focus on parenting stress. The relations were explored in a sample consisting of mothers of 436 children (M_age = 7 years) in Sweden. Half the sample had had early clinical contacts during infancy due to child regulation problems, and the rest were mothers without known such early contacts. Demographic factors, family stressors, and parenting stress were examined in stress – adjustment models. Family stressors were clinical contact during infancy, current child and parent health problems, recent negative life events, and insufficient social support. Parenting stress as a mediator of the effect of other stressors on rated child adjustment was tested as was social support as a moderator of the effect of parenting stress on adjustment. The results showed that a higher parenting stress level was associated with maternal ratings of more externalizing and internalizing behaviors, more social inhibition, and lower social competence. Other family stressors and background variables were also found to be of importance, mainly for externalizing and internalizing problems and to some extent for social competence. Social inhibition had a unique relation to parenting stress only. Parenting stress mediated effects of other stressors in twelve models, whereas social support had no moderating effect on the link between parenting stress and child adjustment. Thus, parenting stress seems to be an important overarching construct. Clinical implications are proposed.
