Gaze following: why (not) learn it?

We propose a computational model of the emergence of gaze following skills in infant-caregiver interactions. The model is based on the idea that infants learn that monitoring their caregiver's direction of gaze allows them to predict the locations of interesting objects or events in their environment (Moore & Corkum, 1994). Elaborating on this theory, we demonstrate that a specific Basic Set of structures and mechanisms is sufficient for gaze following to emerge. This Basic Set includes the infant's perceptual skills and preferences, habituation and reward-driven learning, and a structured social environment featuring a caregiver who tends to look at things the infant will find interesting. We review evidence that all elements of the Basic Set are established well before the relevant gaze following skills emerge. We evaluate the model in a series of simulations and show that it can account for typical development. We also demonstrate that plausible alterations of model parameters, motivated by findings on two different developmental disorders - autism and Williams syndrome - produce delays or deficits in the emergence of gaze following. The model makes a number of testable predictions. In addition, it opens a new perspective for theorizing about cross-species differences in gaze following.     

Does self-consciousness mediate the relation between self-talk and self-knowledge?

Building on Morin's understanding of the relations among self-talk, self-consciousness, and self-knowledge, this study examined the hypothesis that functional and dysfunctional self-consciousness mediate between self-talk and self-knowledge. A self-report questionnaire including 10 scales assessing different aspects of Self-talk, Self-consciousness, and Self-knowledge was administered to 200 German undergraduate university students (95 women, 105 men). Mediation analysis showed that the observed negative relationship between Self-talk and Self-knowledge was mediated by Dysfunctional Self-consciousness, while Functional Self-consciousness acted like a supressor variable. The discussion focuses on limitations of the present measures of Self-talk.     

Stereotype reactance at the bargaining table: the effect of stereotype activation and power on claiming and creating value

Two experiments explored the hypothesis that the impact of activating gender stereotypes on negotiated agreements in mixed-gender negotiations depends on the manner in which the stereo-type is activated (explicitly vs. implicitly) and the content of the stereotype (linking negotiation performance to stereotypically male vs. stereotypically female traits). Specifically, two experiments investigated the generality and limits of stereotype reactance. The results of Experiment 1 suggest that negotiated outcomes become more one-sided in favor of the high power negotiator when masculine traits are explicitly linked to negotiator effectiveness. In contrast, the results of Experiment 2 suggest that negotiated outcomes are more integrative (win-win) when feminine traits are explicitly linked to negotiator effectiveness. In total, performance in mixed-gender negotiations is strongly affected by the cognitions and motivations that negotiators bring to the bargaining table.     

Depression in later life: cross-sequential patterns and possible determinants

Research on the relationship between age and depression has not yielded a consistent picture. Approaches emphasizing resilience compete with assumptions of an increased incidence of depressive problems in later life. This study investigated these issues within a research format combining cross-sectional and 8-year longitudinal assessments of depressive tendencies (690 participants, aged 54-77 years). The developmental patterns suggest 2 phases: Relative stability extending to about 70 years and a subsequent increase of depressive tendencies. Antecedent and mediating factors were explored within a broader context of variables (health status, social and economic resources, coping competences, and future perspectives). Differences in time perspective and a disposition of accommodative flexibility predicted subsequent changes in depression and mediated age effects in depressive tendencies.     

Coping with deficits and losses in later life: from compensatory action to accommodation

Processes of coping with performance deficits in different domains of functioning were investigated in a 4-year longitudinal study involving a core sample of 762 participants (initial age range: 58-81 years). Compensatory efforts to counteract functional impairments were found to increase up to the age of 70 years. Above that age, a decrease in compensatory efforts was observed that was linked to a decrease in the availability and efficiency of action resources. Contentment with actual performance levels remained stable across the entire age range of the study. Stability of self-evaluations was found to depend on adjustment of personal standards: Scarce action resources were accompanied by a lowering of personal comparison standards and by a downgrading of the importance of the respective domains. Accepting more lenient standards of comparison was found to buffer negative effects of performance deficits on contentment with performance among the older participants.     

Age stereotypes in younger and older women: analyses of accommodative shifts with a sentence-priming task

A sentence-priming technique was used to examine whether older women (N = 39) share a more positive view of aging than younger women (N = 35). Situationally specified statements about older and younger persons were presented, followed either by a semantically related word, an unrelated word of the same valence, or a nonword. The accessibility of target words was measured by reaction times in a lexical decision task. Whereas a semantic priming effect for negatively connoted materials emerged for both groups, a priming effect for positively connoted materials was found for older women only. Furthermore, an affective priming effect was found for the older group, i.e., older women tended to respond relatively faster (slower) to semantically unrelated positive (negative) words following a sentence about an older person. The results are discussed within a coping-theoretical framework.

Localizing the first position of a moving stimulus: The Fröhlich effect and an attention-shifting explanation

When subjects are asked to determine where a fast-moving stimulus enters a window, they typically do not localize the stimulus at the edge, but at some later position within that window (Fröhlich effect). We report five experiments that explored this illusion. An attentional account is tested, assuming that the entrance of the stimulus in the window initiates a focus shift toward it. While this shift is under way, the stimulus moves into the window. Because the first phenomenal (i.e., explicitly reportable) representation of the stimulus will not be available before the end of the focus shift, the stimulus is perceived at some later position. In Experiment 1, we established the Fröhlich effect and showed that its size depends on stimulus parameters such as movement speed and movement direction. In Experiments 2 and 3, we examined the influence of eye movements and tested whether the effect changed when the stimuli were presented within a structural background or when they started from different eccentricities. In Experiments 4 and 5, specific predictions from the attentional model were tested: In Experiment 4 we showed that the processing of the moving stimulus benefits from a preceding peripheral cue indicating the starting position of the subsequent movement, which induces a preliminary focus shift to the position where the moving stimulus would appear. As a consequence the Fröhlich effect was reduced. Using a detection task in Experiment 5, we showed that feature information about the moving stimulus is lost when it falls into the critical interval of the attention shift. In conclusion, the present attentional account shows that selection mechanisms are not exclusively space based; rather, they can establish a spatial representation that is also used for perceptual judgment—that is, selection mechanisms can bespace establishing as well.
