Children and television advertising: when do they understand persuasive intent?

Children's response to television advertising is investigated in this paper. Children aged between six and ten years were tested for their recall, recognition and understanding of novel television advertisements. Children were able to recognise scenes from the advertisements after one exposure but recall of the brand names was poor for the younger children, even after three exposures. Recall for the advertising content increased by age and number of exposures. None of the six‐year‐olds and only a quarter of the eight‐year‐olds and a third of the ten‐year‐olds discussed advertising in terms of persuasion. Therefore, although children remember television advertisements, their purpose is not fully understood, even by many ten‐year‐olds. Copyright © 2002 Henry Stewart Publications.     

Aggressive behaviors of the japanese brown bear

Film analysis and direct observation suggest that 2 very different types of intra-specific fights occur among Japanese brown bears maintained in large stable colonies. Disputes arising over food are short, and involve such activities as threatening, muzzling, chasing, and flight. Weapon use during feeding fights primarily involves slashing blows to the back or head areas of the opponent. In contrast, “spontaneous” fights are longer, and consist almost exclusively of wrestling, with bites and forepaw blows directed at the opponent's ruff area. These spontaneous fights occur primarily among the larger and higher-ranked male bears, especially among animals with closely adjacent rankings. It is suggested that such fights facilitate the establishment of dominance relationships by providing an opportunity for mutual assessment of strength and stamina without serious risk of injury.     

Olfactory hedonic context affects both self-report and behavioural indices of palatability

Prior exposure to either a pleasant or unpleasant context may affect later hedonic judgments of a common target stimulus. We explored whether this effect translates into behaviour in the chemical senses. In experiment 1 participants experienced either a pleasant or unpleasant set of odours or pictures, followed by an unfamiliar odour. After self-report hedonic evaluations of the odour, participants were allowed to drink it in solution, followed by a further evaluation of its flavour. Participants reported liking the odour less after smelling pleasant odours and drank less of it too, relative to the unpleasant context. There was no differential context effect for emotive pictures. Experiment 2 replicated these effects, but also included a no-context control. This revealed that the consumption effect was localised to the pleasant olfactory context, whilst contextual effects for liking ratings were primarily localised to the unpleasant olfactory context. In conclusion, hedonic context affects both self-report and behaviour, but not in the same way.     

Race categorization modulates holistic face encoding

Recent studies have shown that same-race (SR) faces are processed more holistically than other-race (OR) faces, a difference that may underlie the greater difficulty at recognizing OR than SR faces (the "other-race effect"). This article provides original evidence suggesting that the holistic processing of faces may be sensitive to the observers' racial categorization of the face. In Experiment 1, Caucasian participants performed a face-composite task with Caucasian faces, Asian faces, and racially ambiguous morphed face stimuli. Identical morphed face stimuli were processed more holistically when categorized as SR than as OR faces. Experiment 2 further suggests that this finding was not underlain by strategic or training effects. Overall, these results support the view that one's categorization of a face as belonging to the same or another race plays a critical role in the holistic processing of this face.     

Parenting after Weight Loss Surgery: A Conceptual Model and Two Case Reports

The ways families approach eating, shape, and weight can result in stress for individual family members and challenge the overall functioning of the family. This is further complicated among families with a parent who has history of obesity or undergone weight loss surgery (WLS). Although WLS can positively impact other family members, it can also exacerbate conflicts regarding feeding and weight. Such conflicts can involve uncertainty regarding the extent to which the entire family should make the dietary changes recommended for the post-WLS parent. Conflict might also center on the appropriate level of concern regarding the children’s risk of developing (or maintaining) obesity. This paper uses two case examples to describe the application of a specialized, time-limited intervention: Parent-Based Prevention following Bariatric Surgery (PBP-B). The program was developed to address the unique challenges and concerns that arise after, or are exacerbated by, WLS. Each detailed case example illustrates a common child-feeding challenge and the employment of key PBP-B strategies throughout the course of treatment. In the first case, the parent who had undergone WLS believed the family’s current eating behaviors were the same as those that had led to her own overeating, obesity, and co-occurring psychiatric symptoms, while her husband disagreed. In the second case, both parents were concerned about their son’s weight, yet due to their prior eating histories, they felt unable to construct boundaries around the feeding experience. Both cases follow families through the entire intervention and illustrate key points and challenges. These cases underscore the need for novel treatment modalities to support families following parental WLS.     

Stepparents’ Attachment Orientation,Parental Gatekeeping,and Stepparents’ Affinity-Seeking with Stepchildren

Remarried stepfamilies are a sizable portion of American families; in a 2011 Pew Center survey, 42% of respondents reported at least one stepfamily member. Family clinicians and researchers suggest that stepparents’ ability to develop close bonds with stepchildren may be critical to the well-being of couple and family relationships. Using actor-partner interdependence models to analyze dyadic data from 291 heterosexual remarried stepfamily couples, we explored factors related to stepparents’ efforts to befriend their stepchildren. Specifically, we evaluated how remarried parents’ gatekeeping and stepparents’ perceptions of their attachment orientations were associated with their own and their spouse's perceptions of stepparents’ affinity-seeking behaviors. Securely attached stepparents and stepparents with anxious attachment orientations engaged more frequently in affinity behaviors than did stepparents with avoidant attachment orientations; there was no difference between securely attached and anxious stepparents. Stepparents’ reports of parents’ restrictive gatekeeping were strongly and negatively associated with both stepparents’ and parents’ reports of stepparent affinity-seeking (actor and partner effects). Parents’ reports of their own restrictive gatekeeping were also negatively (but more weakly) associated with parents’ reports of stepparent affinity-seeking. Implications for families, clinicians, and relationship researchers and theorists are discussed.     

Functions of the vibrissae in the defensive and aggressive behavior of the rat

Removal of mystacial vibrissae for strange rats placed in an established rat colony produced reliable decrements in defensive boxing for these animals, and corresponding increases in freezing. In a subsequent experiment, removal of the vibrissae of the attacking colony males did not change the attack behavior of the vibrissectomized animals. These results indicate that the vibrissae are involved in defensive boxing behavior, but play no essential role in the elicitation or maintenance of conspecific attack in the rat.     

Reflexive fighting in the albino rat: Aggressive or defensive behavior?

Specific agonistic responses of albino rats were compared for dominant colony rats and intruders, and for rats in a “reflexive fighting” task. The “reflexive fighters” showed high levels of defensive responses such as boxing and freezing, and very low levels of aggressive behaviors such as piloerection, biting, and the lateral display. This pattern clearly suggests that the behaviors measured in the reflexive fighting task reflect conspecific defensive reactions, rather than “shockelicited aggression.” Moreover, striking responses seen in the reflexive fighting task also occur at a high rate when footshock is given to a solitary rat held in a boxing posture. Thus it appears that “reflexive fighting” primarily involves defensive rather than aggressive responses.     

Target—distractor interference in the attentional blink implicates the locus coeruleus—norepinephrine system

We provide evidence that the locus coeruleus—norephinephrine (LC-NE) system is the neurophysiological basis of the attentional blink. The attentional blink refers to decreased accuracy for reporting the second of two targets in a rapid serial visual presentation of distractors. The LC-NE account of the attentional blink posits that targets elicit a facilitative LC-NE system response that is available for the first target but subsequently unavailable to the second, due to the autoinhibitory nature of the LC-NE system. We propose a modification of the LC-NE account, suggesting that the LC-NE system response is elicited by interference between mutually exclusive responses demanded by temporally proximal targets and distractors. We increased the interference between the first target and the following distractor by reducing the time between them. For identifying the second target this high-interference condition yielded a benefit up to 200 msec after onset of the first, followed by a decrease in accuracy. Consistent with our modification of the LC-NE account, this result suggests a temporarily enhanced LC-NE system response to increased target—distractor interference.
