Ideal selves and self‐esteem in people with independent or interdependent self‐construal

Not living up to one's ideal self has been shown to coincide with decreased self‐esteem. In the present paper, this notion is applied to the differentiation between people with independent versus interdependent self‐construal. We suggest that the ideal self of independents differs in two respects from the one of interdependents: with respect to its contents (autonomous versus social self‐knowledge) and with respect to the degree of context‐dependency of the encoded knowledge (context‐independent versus context‐dependent self‐knowledge). In three studies, via a priming we either manipulated contents or degree of context‐dependency of what participants considered themselves to actually be like. On both explicit and implicit measures, participants with independent construal indicated higher self‐esteem after priming of autonomous and context‐independent knowledge than after priming of social and context‐dependent knowledge. The opposite pattern was observed in participants with interdependent construal. Results suggest that independent and interdependent construals mirror different ideals which are applied as a comparison standard when evaluating the self.

Two‐year‐old children but not domestic dogs understand communicative intentions without language,gestures, or gaze

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2‐year‐old children but not dogs understood the experimenter's act in intentional conditions. While ostensive pulling of the rope made no difference to children's success, it actually hindered dogs' performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalizations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co‐presence is not possible.     

Attention and ageing: Measuring effects of involuntary and voluntary orienting in isolation and in combination

The cueing paradigm provides an established method for eliciting involuntary and voluntary attention shifts. Involuntary orienting is traditionally measured with non‐predictive peripheral cues and voluntary orienting with predictive central arrows. Recent studies with young adults have established that predictive central arrows trigger a combination of involuntary and voluntary orienting, raising the possibility that previous studies – including those with older adults – misinterpreted their findings with central arrow cues as isolating the effects of voluntary attention. The present experiment applied different cueing conditions that measured involuntary orienting, voluntary orienting, and involuntary and voluntary orienting in combination in older adults. The results show that past studies of voluntary orienting in older adults confound involuntary and voluntary orienting. Cueing effects in a condition that for the first time isolated voluntary orienting (predictive number cues) with older adults were significant, and comparable to effects for younger adults, demonstrating that older adults successfully utilize cues to direct their spatial attention strategically. A similar normal pattern of orienting was observed for involuntary orienting. Our study provides a methodology that can be applied effectively to isolate and investigate the effects of age on voluntary and involuntary attention.

How Do Geneticists and Genetic Counselors Counsel Women from High-Risk Breast Cancer Families?

This qualitative study asked Australian Genetic Counselors and Clinical Geneticists working in cancer genetics to describe their practice when a woman attends a consultation about her family history and her risk of developing breast cancer. Twenty-nine out of 36 Clinical Geneticists/Genetic Counselors returned the questionnaire (82%). Participants identified the key goals of the consultation as (a) identifying the individual needs and concerns of the woman, (b) providing information on genes and chromosomes, (c) giving an individual risk assessment in the context of supportive interaction, and (d) discussing the pros and cons of genetic testing and putting a surveillance plan into place. Respondents emphasized the dual importance of counseling/support and information provision in this setting, suggesting that one could not be given without the other. Implications for clinical practice are discussed.     

What mediation analysis can (not) do

The present article is concerned with a common misunderstanding in the interpretation of statistical mediation analyses. These procedures can be sensibly used to examine the degree to which a third variable (Z) accounts for the influence of an independent (X) on a dependent variable (Y) conditional on the assumption that Z actually is a mediator. However, conversely, a significant mediation analysis result does not prove that Z is a mediator. This obvious but often neglected insight is substantiated in a simulation study. Using different causal models for generating Z (genuine mediator, spurious mediator, correlate of the dependent measure, manipulation check) it is shown that significant mediation tests do not allow researchers to identify unique mediators, or to distinguish between alternative causal models. This basic insight, although well understood by experts in statistics, is persistently ignored in the empirical literature and in the reviewing process of even the most selective journals.     

Does temporal preparation increase the rate of sensory information accumulation?

Recent studies showed that temporal preparation, i.e., the ability to prepare for an upcoming stimulus, improves perceptual processing. The mechanisms underlying this benefit are still controversial. Based upon the theoretical framework of accumulation models, it has been proposed that the accumulation of sensory stimulus information begins earlier when participants are temporally prepared than when they are unprepared. Alternatively, however, temporal preparation might also affect the accumulation rate of sensory information. In the present study, we examined these possibilities. Specifically, in three experiments, we manipulated participants' decision criterion. This manipulation should interact with any experimental manipulation affecting the rate of information processing, but produce additive effects with any manipulation affecting the onset of information accumulation rather than its rate. We obtained additive effects on RT, irrespective of whether the decision criterion was manipulated by increasing catch trial proportion or nogo trial proportion. These results suggest that temporal preparation improves perceptual processing by operating on the onset of sensory information accumulation rather than the rate of sensory information accumulation.     

Development of a 15-item odour discrimination test (Düsseldorf Odour Discrimination Test)

A key function of the olfactory system is the detection of differences in odour quality. Therefore, a test was developed to assess odour discrimination ability in normosmic humans. Out of six monomolecular substances (capric acid, coumarin, eugenol, geraniol, phenylethyl alcohol, and vanillin) quaternary mixtures were prepared. Within one item, three odour mixtures were presented (triangle forced-choice procedure). The deviant odour contained the same substances as the two remaining odours; however, the proportions were changed. Study 1 (120 participants) aimed to select items that contribute to a high internal consistency. Study 2 (104 participants) assessed test-retest reliability, parallel test reliability and test validity. Out of 45 items, a 15-item test (Düsseldorf Odour Discrimination Test, DODT) with an internal consistency of 0.61 and medium item difficulties was prepared. The test-retest reliability of the DODT was 0.66 (test interval = 4 weeks) and the parallel test reliability 0.42. The DODT correlated significantly with the University of Pennsylvania Smell Identification Test and to a lesser extent with the phenylethyl alcohol odour threshold test. As the DODT did not correlate with the odour discrimination test of the Sniffin' Sticks, the two tests seem to measure different performances of the olfactory system.     

The role of source memory in older adults' recollective experience

Younger adults' "remember" judgments are accompanied by better memory for the source of an item than "know" judgments. Furthermore, remember judgments are not merely associated with better memory for individual source features but also with bound memory for multiple source features. However, older adults, independent of their subjective memory experience, are generally less likely to "bind" source features to an item and to each other in memory (i.e., the associative deficit). In two experiments, we tested whether memory for perceptual source features, independently or bound, is also the basis for older adults' remember responses or if their associative deficit leads them to base their responses on other types of information. The results suggest that retrieval of perceptual source features, individually or bound, forms the basis for younger but not for older adults' remember judgments even when the overall level of memory for perceptual sources is closely equated (Experiment 1) and when attention is explicitly directed to the source information at encoding (Experiment 2).
