May I have your attention please: Binding of attended but response-irrelevant features

The feature codes of stimuli and responses can be integrated, and if a stimulus is repeated it can retrieve the previously integrated response. Furthermore, even irrelevant features can be integrated and, upon repetition, retrieve the response. Yet the role of attention in feature integration and retrieval is not clearly understood. Some theories assume a central role of attention (e.g., Logan, 1988; Treisman & Gelade, 1980), but other studies have shown no influence of attention on feature binding (e.g., Hommel, 2005). In the present experiments the effect of attention on the integration of two different response-irrelevant features of the same stimulus was examined. In two experiments, participants responded to the color (response feature) of word stimuli, while two irrelevant features of the words (word type and valence) were systematically varied. Participants’ attention was directed to either one or the other of the response-irrelevant features by asking participants to report that feature at the end of the trial. Feature–response binding effects in the color task were observed to be stronger for the attended response-irrelevant feature. These results indicate that feature binding is not only very flexible but also sensitive to the distribution of attention. It is also automatic, in the sense that as long as attention is available, feature binding occurs irrespective of the task-specific demands.     

A Protection Motivation Theory application to date rape education

Date rape risk communication is a key component of education-based Date Rape Prevention Programs, common across colleges. In such programs, risk assessment in date rape is approached cautiously in order to avoid a tone of "victim blaming." Since it is important in the assessment of any risk to understand the surrounding social context of the risky situation and the individual's unique relationship with that social context, this study examines Protection Motivation Theory as it applies to handling the risk of date rape without victim blaming. The paper links individual personality and social contexts with risk communication. The study sample comprised 367 undergraduate women enrolled in a large Southern Public University. The study examines the relationships between dating activity, social competency, and type of information provided with the dependents variables of date rape related protection behavior (intent), belief, and knowledge. A factorial multiple analysis of covariance analysis found that the dependent variables had a significant relationship with aspects of social competency and dating activity. The exposure to varying information about date rape was not significantly related to the dependent variables of date rape-related protection behavior (intent), belief, and knowledge. The identification of social competency and dating activity status as protective factors in this study makes a significant contribution to the practice and research efforts in date rape education.     

Rapid reacquisition of native phoneme contrasts after disuse: you do not always lose what you do not use

Infants attune to their birth language during the second half of infancy. However, internationally adopted children are often uniquely required to attune to their birth language, and then reattune to their adoptive language. Children who were adopted from India into America at ages 6-60 months (N = 8) and had minimal further exposure to their birth languages were compared to age-matched American non-adopted controls. Without training, neither group could discriminate a phonemic contrast that occurs in their birth language but not in English. However, after training on the contrast, the adopted group (N = 8) improved significantly and discriminated the contrast more accurately than their non-adopted peers. While English had explicitly replaced the birth language of the adopted sample, traces of early exposure conferred privileges on subsequent learning. These findings are consistent with behavioral and neurophysiological data from animals that have identified some of the mechanisms underlying such a 'retention without further use' phenomenon.     

Revalidation of the <Emphasis Type="Italic">Sat</Emphasis>-<Emphasis Type="Italic">Chit</Emphasis>-<Emphasis Type="Italic">Ananda</Emphasis> Scale

Sat-Chit-Ananda is an indigenous construct that refers to absolute bliss and consciousness. The present study aimed to strengthen the psychometric properties of the newly developed Sat-Chit-Ananda scale (Singh et al. in Int J Vedic Found Manag 1(2):54–74, 2014). A total of 398 students aged 17–36 years (mean age = 21.33 years, SD = 2.2, 70% males) participated in this study. An exploratory as well as confirmatory factor analysis was computed for the 17-item scale. Its’ concurrent validity was established by assessing its correlation with other well-being measures, namely Flourishing (Diener et al. in Soc Indic Res 97:143–156 2010) and Scale of Positive and Negative Experience (Diener et al. 2010). Satisfactory results were obtained from both exploratory and confirmatory factor analyses. Sat-Chit-Ananda and its factors were found to be significantly positively correlated with Flourishing and Positive Experiences and were negatively correlated with Negative Experiences. Thus, the validity of the Sat-Chit-Ananda (Singh et al. 2014) scale stands further substantiated—offering this scale as a promising new assessment tool.     

Positive affect as a moderator of liking effects on trust and attraction

Attitude similarity effects on attraction appear to be mediated sequentially by positive affect, inferred attraction, and trust. That is, the first two supposedly distal mediators influence each other in building trust, a mediator proximal to attraction. However, the correlational nature of data reported heretofore precludes definitive conclusions about sequential dependency between the two distal mediators. In the research reported, therefore, the authors manipulated positive affect in the participants (Time 1) and liking of the partner for them (Time 2), and measured trust before attraction. As predicted, liking effects on trust and attraction were stronger when positive affect in the participants was high than when it was low. Importantly, the interaction effect in trust fully mediated the interaction effect in attraction.     

Public approval of suicide: a situational analysis

Using four national surveys conducted in 1977, 1978, 1982, and 1983, this study examined public opinions on suicide in four situations: incurable disease, bankruptcy, family dishonor, and being tired of living. The results indicated that suicide in case of incurable disease was approved by slightly less than 43%, being tired of living by about 13%, and the other two situations by 7%. It was found that respondents with attributes of higher education, lower religiosity, and higher commitment to freedom of expression were more likely to consider suicide as acceptable. Future implications for research suggest not only an assessment of attitudes toward suicide in different situational contexts, but also assessment of individual intentions for the situations considered in this study.     

Independent and social play among profoundly mentally retarded adults: training, maintenance, generalization, and long-term follow-up.

Play skills were taught to eight profoundly mentally retarded adults in two interrelated experiments. In Experiment 1, a multiple baseline across subjects design was used to assess the efficacy of verbal and physical prompts on independent play. In Experiment 2, the same subjects and experimental procedures were used to develop social play. Verbal prompting and graduated physical guidance procedures were found to be effective in substantially increasing independent play in Experiment 1 and social play in Experiment 2. Positive changes were also observed in collateral behaviors. Inappropriate play decreased slightly and stereotypy decreased to very low levels. Social interaction increased substantially in Experiment 2 when social play was targeted but little change was observed in Experiment 1 when only independent play was targeted. Treatment gains were maintained for 26 weeks in Experiment 1 and 10 weeks in Experiment 2. In addition, the treatment gains were generalized across subjects and settings in Experiment 2. Finally, regular follow-up checks showed that independent and social play remained in the repertoire of the subjects for 12 months following the termination of programmed maintenance.     

The role of brain-derived neurotrophic factor genotype, parental depression, and relationship discord in predicting early-emerging negative emotionality

The brain-derived neurotrophic factor (BDNF) gene is a plausible candidate for early-emerging negative emotionality (NE), and evidence suggests that the effects of this gene may be especially salient in the context of familial risk for child maladjustment. We therefore examined whether the single-nucleotide polymorphism producing a valine-to-methionine substitution at codon 66 (val66met) of the BDNF gene was associated with childhood NE, in the context of parental depression and relationship discord. A sample of 413 three-year-old children was assessed for NE using standardized laboratory measures. The children's parents completed clinical interviews as well as a measure of marital satisfaction. Children with at least one BDNF methionine (met) allele exhibited elevated NE when a parent had a history of depressive disorder or when relationship discord was reported by a parent. In contrast, this allele was associated with especially low NE when parental depression was absent and when the parental relationship was not discordant. Our findings suggest that the BDNF met allele confers increased child sensitivity to both positive and negative familial influences.
