Stronger evidence for own-age effects in memory for older as compared to younger adults

Three studies examined whether younger and older adults better recall information associated with their own than information related to another age group. All studies compared young and older adults with respect to incidental memory for previously presented stimuli (Studies 1 and 2: everyday objects; Study 3: vacation advertisements) that had been randomly paired with an age-related cue (e.g., photo of a young or an old person; the word "young" or "old"). All three studies found the expected interaction of participants' age and age-associated information. Studies 1 and 2 showed that the memory bias for information arbitrarily associated with one's own as compared to another age group was significant for older adults only. However, when age-relevance was introduced in a context of equal importance to younger and older adults (information about vacations paired either with pictures of young or older adults), the memory bias for one's own age group was clearly present for both younger and older adults (Study 3).     

“Feeling” the pain of those who are different from us: Modulation of EEG in the mu/alpha range

We explored how apparently painful stimuli and the ability to identify with the person on whom the pain is inflicted modulate EEG suppression in the mu/alpha range (8–12 Hz). In a 2 × 2 design, we presented pictures of hands either experiencing needle pricks or being touched by a Q-tip. In the dissimilar-other condition, the hand was assigned to a patient suffering from a neurological disease in which Q-tips inflicted pain, whereas needle pricks did not. In the similar-other condition, the hand was assigned to a patient who responded to stimulation in the same way as the healthy participant. Participants were instructed to imagine the feeling of the person whose hand was shown and to evaluate his or her affective state. Pain conditions elicited greater EEG suppression than did nonpain conditions, particularly over frontocentral regions. Moreover, an interaction between pain and similarity revealed that for similar others, the pain effect was significant, whereas in the dissimilar-other group, suppression was equally large in the pain and no-pain conditions. We conclude that mu/alpha suppression is elicited both automatically, by observing a situation that is potentially painful for the observer, and by empathy for pain, even if the other person is different from oneself.     

Toward a developmental psychology of Sehnsucht (life longings): the optimal (utopian) life

The topic of an optimal or utopian life has received much attention across the humanities and the arts but not in psychology. The German concept of Sehnsucht captures individual and collective thoughts and feelings about one's optimal or utopian life. Sehnsucht (life longings; LLs) is defined as an intense desire for alternative states and realizations of life. Presenting a first effort at capturing this phenomenon, the authors conceptualize LLs as composed of 6 interrelated core characteristics: (a) utopian conceptions of ideal development; (b) sense of incompleteness and imperfection of life; (c) conjoint time focus on the past, present, and future; (d) ambivalent (bittersweet) emotions; (e) reflection and evaluation of one's life; and (f) symbolic richness. Self-report data from 299 adults (19-81 years) support the postulated structure and support predictions regarding the functional role of Sehnsucht. Having LLs was evaluated as providing direction to development and helping to manage life's incompleteness. At the same time, the frequent and intense experience of LLs was associated with lower well-being. When LLs were perceived as controllable, however, this negative association disappeared.     

Gender differences in global-local perception? Evidence from orientation and shape judgments

Direct examinations of gender differences in global-local processing are sparse, and the results are inconsistent. We examined this issue with a visuospatial judgment task and with a shape judgment task. Women and men were presented with hierarchical stimuli that varied in closure (open or closed shape) or in line orientation (oblique or horizontal/vertical) at the global or local level. The task was to classify the stimuli on the basis of the variation at the global level (global classification) or at the local level (local classification). Women’s classification by closure (global or local) was more accurate than men’s for stimuli that varied in closure on both levels, suggesting a female advantage in discriminating shape properties. No gender differences were observed in global-local processing bias. Women and men exhibited a global advantage, and they did not differ in their speed of global or local classification, with only one exception. Women were slower than men in local classification by orientation when the to-be-classified lines were embedded in a global line with a different orientation. This finding suggests that women are more distracted than men by misleading global oriented context when performing local orientation judgments, perhaps because women and men differ in their ability to use cognitive schemes to compensate for the distracting effects of the global context. Our findings further suggest that whether or not gender differences arise depends not only on the nature of the visual task but also on the visual context.     

The freezing and unfreezing of lay-inferences: Effects on impressional primacy,ethnic stereotyping,and numerical anchoring

Three experiments were conducted to test the hypothesis that primacy effects, ethnic stereotyping, and numerical anchoring all represent “epistemic freezing” in which the lay-knower becomes less aware of plausible alternative hypotheses and/or inconsistent bits of evidence competing with a given judgment. It was hypothesized that epistemic freezing would increase with an increase in time pressure on the lay-knower to make a judgment and decrease with the layknower's fear that his/her judgment will be evaluated and possibly be in error. Accordingly, it was predicted that primacy effects, ethnic stereotyping, and anchoring phenomena would increase in magnitude with an increase in time pressure and decrease in magnitude with an increase in evaluation apprehension. Finally, the time-pressure variations were expected to have greater impact upon “freezing” when the evaluation apprehension is high as opposed to low. All hypotheses were supported in each of the presently executed studies.     

A note on erotic arousal value of moving and stationary human forms

For subhuman vertebrates there already exists a huge body of information on male and female courtship behaviour and in many instances the impact of movement patterns on the prospective partner has been assessed. However, little information is available on the erotic impact of human movement patterns.In analysing erotic preferences by means of the phallometric method, moving vs. still pictures has been a factor in a variety of studies. Kolá?ský and Madlafousek (1973) compared the erotic responses of normal and sexually deviant males to filmed courtship behaviour, non-erotic activities and stills of the same female. They found that dynamically presented filmed courtship patterns were more arousing for normal heterosexual males than stills on which no particular activity was shown, and that these stills were more arousing than movie pictures of nonerotic activities.In a study of classical conditioning, McConaghy (1970) found he could not condition positive penile responses to geometric figures when using still pictures of nude females as unconditioned stimuli, but that this was possible when using movies. He concluded that the movie pictures had a greater impact on his Ss than the stills and supported this impression with another study in which he compared responses to movies and stills of nude females (McConaghy, 1973). However, the persons on the movies were not identical with those on the stills and the depicted behavioural configurations varied widely. In the following study, results are reported on the erotic value of a relatively simple movement pattern, namely walking towards the viewer and smiling, vs. a still picture of the same person smiling.     

Experimental analysis of pedophilia

It was hypothesized that the population of pedophiles differs from that of males who prefer physically mature partners, in respect of the proportion of bisexual members in each group. Bisexuality was assessed by means of a verbal scale and by recording penile volume changes during the presentation of movie clips of nude males and females. Results supported the hypothesis.An earlier finding of a difference between pedophiles and males who prefer physically mature partners, in respect to feminine gender identity, was retested using the Feminine Gender Identity Scale (for males). It could be confirmed only for homosexual males and therefore cannot be accepted as a general difference between pedophiles and persons who prefer physically mature partners.     

Spatio-temporal organization during group formation in rats

In the present study, the dynamic process of group formation in eight unfamiliar rats was followed in order to reveal how the group becomes oriented together in time and space, in light of the complexity that accompanies grouping. The focus was on who, where, and when joined together. We found that rats preferred to be in companionship over remaining alone, with all the rats gradually shifting to share the same location as a resting place. Group formation can be viewed as a tri-phasic process, with some rats gradually becoming more social than others, and thus playing a key role in group formation. Starting with seemingly independent traveling, the rats gradually converged to share the same location as a terminal (home base) for roundtrips in the arena. Because such a terminal is considered as the organizer of an individual’s spatial behavior, the shared home-base location may be viewed as the organizer of spatial behavior of the entire group. Despite huddling together, the rats continued to travel alone or in duos throughout the 3 h of testing. We suggest that resting together and traveling alone or in duos enabled the maintenance of communal relationship while reducing the complexity involved in traveling in relatively large groups. Taken together, the present results demonstrate the dynamic process during which unfamiliar rats shift from independent to group spatial behavior.
