This study examines relationships between constructs based on two perspectives on the development of self‐governance, namely Self‐Determination Theory (SDT; Deci & Ryan, 2000) and Berzonsky's (1990) identity style model. Theoretically predictable relationships are found between the three causality orientations defined by SDT (autonomous, controlled, and impersonal) and the three identity styles proposed by Berzonsky (informational, normative, diffuse–avoidant) in a sample of Belgian late adolescents. An autonomous causality orientation is positively related to an informational identity style and negatively related to a diffuse–avoidant style. A controlled orientation is positively associated with a normative identity style, and an impersonal orientation is positively related to a diffuse–avoidant identity style. Participants' gender does not moderate these relationships. The findings suggest that the causality orientations late adolescents employ may play an important role in how actively and thoroughly they explore identity‐relevant issues.

Previous research has documented a tendency for people to make more risk‐seeking decisions for others than for themselves in relationship scenarios. Two experiments investigated whether this self–other difference is moderated by participants' self‐esteem and anxiety levels. In Experiment 1, lower self‐esteem and higher anxiety levels were associated with more risk‐averse choices for personal decisions but not for decisions for others. Therefore, participants with lower self‐esteem/higher anxiety showed greater self–other differences in comparison to participants with higher self‐esteem/lower anxiety levels. Experiment 2 demonstrated that this effect was largely mediated by participants' expectations of success and feelings about potential negative outcomes. These results are discussed in the context of “threats to the self,” with a central role played by anxiety and self‐esteem threats in personal decision making but not in decision making for others.

With a ‘split ad’, information is presented as two distinct parts, such as when two short commercials for a given brand are separated by other television content. Two studies are presented in this paper which demonstrate the advantages of an emerging form of the split ad strategy, which is termed the ‘hybrid split ad’ technique. Using this approach, a message typically begins in a traditional medium and then concludes at a website. In Experiment 1, the hybrid split ad technique is shown to enhance attitudes towards an advertised product by increasing the perceived importance of favourable attributes provided at the website. Experiment 2 replicates this finding and also addresses an issue of managerial importance, namely, how to motivate consumers to pursue the second (web‐based) portion of the ad. Offering consumers an incentive at the website is useful in this regard, provided that the incentive is small enough not to undermine the positive effects of the hybrid split ad. 相似文献

Theory of mind studies of emotion usually focus on children's ability to predict other people's feelings. This study examined children's spontaneous references to mental states in explaining others' emotions. Children (4‐, 6‐ and 10‐year‐olds, n = 122) were told stories and asked to explain both typical and atypical emotional reactions of characters. Because atypical emotional reactions are unexpected, we hypothesized that children would be more likely to refer to mental states, such as desires and beliefs, in explaining them than when explaining typical emotions. From the development of lay theories of emotion, derived the prediction that older children would refer more often to mental states than younger children. The developmental shift from a desire‐psychology to a belief‐psychology led to the expectation that references to desires would increase at an earlier age than references to beliefs. Our findings confirmed these expectations only partly, because the nature of the emotion (happiness, anger, sadness or fear) interacted with these factors. Whereas anger, happiness and sadness mainly evoked desire references, fear evoked more belief references, even in 4‐year‐olds. The fact that other factors besides age can also play an influential role in children's mental state reasoning is discussed. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

The outcome of German serial murderer spatial decision making was measured as the straight‐line distance (km) between murderer home locations and each crime location (i.e. body recovery location). Geographic and series development data, as well as information on age, intelligence, motive, marital status, employment status, and mode of transportation of 53 German serial murderers was collected from police and prosecution service files and judicial verdict records. Potential effects of the aforementioned factors on spatial decisions were assessed. Results showed that 63% of the murderers lived within 10 km of their crime locations. Home‐to‐crime distance was negatively correlated with murderer age and positively correlated with murderer IQ score. Results also showed that the mode of transportation used by murderers had an effect on their spatial decisions. Results are discussed in terms of understanding serial murderer spatial decision‐making and implications for police investigations. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Homicide by wives against husbands is a largely unexplored subject in lethal violence research. The paucity of information on the phenomenon is particularly acute in the non-Western world where scholarly research is virtually nonexistent. The specific goal for this article, then, was to provide additional insights into the issue by investigating wife-to-husband killings that occurred in Ghana, a non-Western society, during 1990-2005. In line with the scant, extant literature, the results of the analysis demonstrate that victims were invariably slain at home. The motive for the crime was to punish a womanizing husband, a husband who had taken another wife, or one who was contemplating wedding another wife in this polygynous society. In other instances, the homicidal intent was to physically eliminate a husband to facilitate an amorous relationship between the assailant and her new lover. In several cases, husband-slayers killed a latent or predisposing victim (e.g. sleeping or ill) via burning, slashing with a machete or food poisoning. The implications of the findings are discussed. 相似文献

Logit and logistic regression analyses were employed to explore the nature, extent and predictors of behaviors indicative of \"being bullied\" and of \"bullying others\" in a sample of 125 adult male offender-patients sectioned for enduring mental illness and detained within a high-secure psychiatric hospital. The study addresses the lack of research into this specialized population to date, with a subsidiary aim of comparing the results directly with a previous study conducted with a population of adult male personality-disordered offender-patients (n = 53). Participants were required to complete a self-report behavioral checklist (Direct and Indirect Patient behavior Checklist-Hospital version Revised). The prediction that indirect (subtle) aggression would be reported more frequently than direct aggression was supported in relation to perpetration estimates, with evidence such aggression was also more prevalent among personality-disordered than mentally ill offender-patients. As predicted verbal aggression was the most commonly reported direct behavior. Although it was predicted that those perpetrating aggression would present with increased experience with secure settings this was only supported with regard to bully-victims. Contrary to the prediction made, those victimized did not present with less experience of secure settings. Consistent with the hypothesis, bully/victims were predicted by increased negative behavior toward staff and hospital rules. The results are discussed in relation to the environment in which the aggression is taking place with the implications for practice and future research outlined. 相似文献

In this study we present a self-organizing connectionist model of early lexical development. We call this model DevLex-II, based on the earlier DevLex model. DevLex-II can simulate a variety of empirical patterns in children's acquisition of words. These include a clear vocabulary spurt, effects of word frequency and length on age of acquisition, and individual differences as a function of phonological short-term memory and associative capacity. Further results from lesioned models indicate developmental plasticity in the network's recovery from damage, in a non-monotonic fashion. We attribute the network's abilities in accounting for lexical development to interactive dynamics in the learning process. In particular, variations displayed by the model in the rate and size of early vocabulary development are modulated by (a) input characteristics, such as word frequency and word length, (b) consolidation of lexical-semantic representation, meaning-form association, and phonological short-term memory, and (c) delayed processes due to interactions among timing, severity, and recoverability of lesion. Together, DevLex and DevLex-II provide an accurate computational account of early lexical development. 相似文献

In this study, we apply MOSAIC (model of syntax acquisition in children) to the simulation of the developmental patterning of children's optional infinitive (OI) errors in 4 languages: English, Dutch, German, and Spanish. MOSAIC, which has already simulated this phenomenon in Dutch and English, now implements a learning mechanism that better reflects the theoretical assumptions underlying it, as well as a chunking mechanism that results in frequent phrases being treated as 1 unit. Using 1, identical model that learns from child-directed speech, we obtain a close quantitative fit to the data from all 4 languages despite there being considerable cross-linguistic and developmental variation in the OI phenomenon. MOSAIC successfully simulates the difference between Spanish (a pro-drop language in which OI errors are virtually absent) and obligatory subject languages that do display the OI phenomenon. It also highlights differences in the OI phenomenon across German and Dutch, 2 closely related languages whose grammar is virtually identical with respect to the relation between finiteness and verb placement. Taken together, these results suggest that (a) cross-linguistic differences in the rates at which children produce OIs are graded, quantitative differences that closely reflect the statistical properties of the input they are exposed to and (b) theories of syntax acquisition need to consider more closely the role of input characteristics as determinants of quantitative differences in the cross-linguistic patterning of phenomena in language acquisition. 相似文献

The study of infant communication during mother–infant interactions has largely focused on infants' distal behaviours, while neglecting their more proximal behaviours, such as touch. Yet, touch is an important modality through which infants and mothers communicate; it is also a vital means through which infants self‐regulate and explore their surroundings. The present study was designed to investigate the touching behaviours of 44, 51/2‐month‐old, healthy, full‐term infants during face‐to‐face mother–infant interactions. A still‐face (SF) procedure was used in order to examine differences in the types and locations of infant touch across normal and perturbed interaction periods, when mothers exhibit changes in their emotional availability. Results revealed that infant touch varied with changes in maternal availability. During the SF period, when mothers were unavailable, infants used more active, soothing, and reactive tactile behaviours (stroke, finger, pat, and pull), and they spent more time touching themselves. In contrast, infants used mostly passive touch (static) during the Normal periods, when their mothers were available. They also spent a significant portion of time touching their mothers. The variations in infant touch across periods suggest that infants communicate their affective states through touch. The findings also support the regulatory and exploratory roles of infant touch, especially during periods of maternal unavailability. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献
