Gender Representation of Older People in Japanese Television Advertisements

This content analysis of 306 Japanese television advertisements featuring older people (50+) analyzed differences in representation based on gender. The results revealed that both genders were underrepresented in comparison to demographic reality. This disparity was even more pronounced for older females, who appeared in less than half as many commercials as did older males. Older females were depicted at home, while their male counterparts were shown in the workplace. Moreover, some product categories were associated with a particular gender: cosmetics/toiletries with females and foods/beverages with males. Many of these findings are in accordance with previous studies from other parts of the world. Adding evidence from Japan lends support to the hypothesis of global gender stereotypes.     

Age differences in processing fluctuations in postural control across trials and across days

Postural control performances of 18 younger and 18 older adults were repeatedly measured on 45 weekdays with five trials per day. This design made it possible to dissociate between long-term trends and processing fluctuations in the sensorimotor domain at moment-to-moment, trial-to-trial, and day-to-day levels. Older adults fluctuated more than younger adults at all timescales. Age differences in trial-to-trial and day-to-day processing fluctuations were reduced but remained statistically significant when controlling for fluctuations on faster timescales. We concluded that age differences in intraindividual fluctuations at the longer timescales are in part related to age differences in low-level system robustness, suggesting a cascade of effects across multiple timescales.     

Environmentalism as a trait: gauging people's prosocial personality in terms of environmental engagement

According to Hardin (1968), environmental deterioration stems from self-interest undermining people's resource conservation in the collective interest. Not surprisingly, selfless prosocial motives, such as personal feelings of moral obligation, have often been recognized as a key force behind people's environmentalism. In our research, we anticipated that environmentalists-people with an inclination for pro-environmental engagement-would possess a propensity to generally act prosocially. In an extension of previous work, we expected that a well-established self-report measure of past conservation behavior would predict people's active participation in a psychological experiment. Based on subjects' degree of environmental engagement, originally established in 2003, we re-contacted a sample of 502 persons in 2005. Of these 502 (68.5% low, 31.5% high in environmentalism), 131 showed up for the announced experiment. Among those participants, we found that environmentalists' prosocial personalities were additionally reflected in their social value orientations. Ninety percent of the environmentalists turned out to be prosocials, whereas only 65% of the less environmentally engaged subjects were prosocials. Overall, our findings lend credit to a notion of environmentalism as an indicator of even subtle quantitative differences in a person's prosocial trait level. By and large, environmentalists acted more prosocially even in mundane activities unrelated to environmental conservation. Additional evidence comes from the commons dilemma experiment in which the participants partook. There, we generally found comparatively more cooperation with others for the collective good from people high in environmentalism. Our findings represent circumstantial evidence for a prosocial propensity dimension along which people differ, and which is also reflected in people's pro-environmental behavioral performance. If, however, environmentalism has to be regarded as indicative of a prosocial trait rather than a state-like motive, high hopes for moral norms and other prosocial motives in environmental conservation do not seem warranted.     

Dyadic drumming across the lifespan reveals a zone of proximal development in children

Many social interactions require the synchronization--be it automatically or intentionally--of one's own behavior with that of others. Using a dyadic drumming paradigm, the authors delineate lifespan differences in interpersonal action synchronization (IAS). Younger children, older children, younger adults, and older adults in same- and mixed-age dyads were instructed to drum in synchrony with their interaction partner at a constant, self-chosen tempo. Adult-only dyads showed the highest and children-only the lowest levels of IAS accuracy. It is important to note that children improved reliably in IAS accuracy when paired with older partners. The observed age-related differences in IAS accuracy remained reliable after statistically controlling for individual differences in the ability to synchronize to a metronome and for between-dyad differences in tempo. The authors conclude that IAS improves from middle childhood to adulthood and that adult interaction partners may facilitate its development.     

Is Self‐Determined Functioning a Universal Prerequisite for Motive–Goal Congruence? Examining the Domain of Achievement in Three Cultures

ABSTRACT Research has shown that capacity for accessing implicit motives promotes congruence between the implicit and the explicit motivational system: Individuals able to test a conscious goal for its fit with their implicit motivation commit themselves more fully to self‐congruent goals. However, it has not yet been shown whether this is a universal phenomenon or limited to Euro‐American cultures in which individual needs are less strictly constrained by the social environment than in other cultural contexts. Thus, the present study examined whether self‐determination interacts with the implicit achievement motive to predict how much importance individuals from Cameroon, Germany, and Hong Kong ascribe to achievement goals. Moreover, the importance ascribed to goals should indirectly predict life satisfaction via success in goal realization. Results showed that the associations described above are valid in all three cultural groups and are discussed in terms of their implications for the universal processes characterizing motivation.     

Environmental knowledge and conservation behavior: exploring prevalence and structure in a representative sample

Knowledge is commonly seen as a necessary precondition for a person’s behavior. Consistent with this, most educational interventions rely on knowledge transfer. However, for the most efficient informational strategies for education, it is essential that we identify the types of knowledge that promote behavior effectively and investigate their structure. A questionnaire consisting of three environmental knowledge scales and a conservation behavior measure was sent to 5000 randomly selected Swiss adults. A completed questionnaire was returned by 55% of them (N=2736). A series of structural equation analyses indicates that the three knowledge forms exert different influences on conservation behavior: Action-related knowledge and effectiveness knowledge have a direct effect on performance. In contrast, system knowledge is more remote from behavior, exerting only a mediated influence on it by way of affecting the other two knowledge types.     

A Matlab function to estimate choice model parameters from paired-comparison data.

Tversky (1972) has proposed a family of models for paired-comparison data that generalize the Bradley-Terry-Luce (BTL) model and can, therefore, apply to a diversity of situations in which the BTL model is doomed to fail. In this article, we present a Matlab function that makes it easy to specify any of these general models (EBA, Pretree, or BTL) and to estimate their parameters. The program eliminates the time-consuming task of constructing the likelihood function by hand for every single model. The usage of the program is illustrated by several examples. Features of the algorithm are outlined. The purpose of this article is to facilitate the use of probabilistic choice models in the analysis of data resulting from paired comparisons.     

Effects of syllable-frequency in lexical decision and naming: an eye-movement study

In three experiments we explored task-specific effects of syllable-frequency, following Perea and Carreiras' (1998) findings of a facilitative effect during naming and an inhibitory effect during lexical decision. In Experiment 1, an inhibitory effect of first syllable-frequency on articulation duration suggested a process-specific effect during naming: a facilitative effect on construction of phonological output, but an inhibitory effect on lexical access. Eye-movement recording was used in Experiment 2 to disentangle these two processes. An inhibitory effect on eye-movement parameters during both lexical decision and naming supported the assumption that higher first syllable-frequency inhibits lexical access. Implications of a general inhibitory effect of syllable-frequency for computational models of word recognition, specifically for the multiple-trace memory (MTM) model of polysyllabic word naming (Ans, Carbonnel, & Valdois, 1998), are discussed.     

Semantic generalization of stimulus-task bindings

People find it difficult to switch between two tasks, even if they have time to prepare—the so-called residual task shift cost. We studied a switch of tasks from picture naming to word reading, using picture-word Stroop stimuli. Consistent with previous findings, we demonstrate that a large part of the observed task shift cost was due to priming from prior stimulus-response episodes, in which the current task stimulus was encountered in a competing task. We further show that this task-priming effect generalizes to semantically related stimuli, which opens the possibility that most or all of these residual shift costs reflect some sort of generalized proactive interference from previous stimulus-task episodes.
