“It’s not funny if they’re laughing”: Self-categorization, social influence, and responses to canned laughter

Pre-recorded, or “canned” laughter is often used to encourage audience laughter. Previous research suggests that hearing others laugh can influence an audience, although several variables moderate its effects. We examined an unexplored moderator, hypothesizing that canned laughter would influence listeners only if they believed the laughter came from fellow in-group members. We manipulated the presence or absence of canned laughter in a potentially humorous recording and participants’ beliefs about the in-group or out-group composition of the laughing audience. The results confirmed our hypothesis: participants laughed and smiled more, laughed longer, and rated humorous material more favorably when they heard in-group laughter rather than out-group laughter or no laughter at all.     

Implicit attitudes towards people with visible difference: findings from an Implicit Association Test

Research on implicit and explicit attitudes towards those with a visible difference has provided contradictory findings. While studies suggest explicit attitudes towards those with a visible difference are positive, implicit attitudes are likely to be negative. An Implicit Association Test measured attitudes towards visible differences in 129 adults finding no evidence of negative implicit attitudes. This contrasts with previous findings and accounts of those with a visible difference who report perceiving negative behaviours by the general public. Results are discussed in terms of what is known about perceiving faces that are different, as well as socio-cultural changes. These findings provide preliminary evidence that implicit attitudes towards visible difference are not negative, and that behaviour may be a result of uncertainty regarding how to behave.     

Counting Chicks Before They Hatch: Female Cowbirds Can Time Readiness of a Host Nest for Parasitism

ABSTRACT— Here we show that demands associated with brood parasitism have favored sophisticated cognitive abilities in female brown-headed cowbirds. We discovered that cowbirds can use the rate at which eggs are added to a nest across days to assess the readiness of the nest for incubation, which would allow them to synchronize laying with the host and avoid nests where incubation has most likely commenced. In three experiments, cowbirds investigated and laid eggs in artificial nests that differed in the number of eggs they contained. Across days, we added eggs to nests at different rates to simulate differences in the timing of reproduction of the hosts. Cowbirds avoided a nest if the number of eggs that had been added was less than the number of days that had elapsed. The ability of females to remember egg number and compare changes in egg number across days allows them to select nests most suitable for parasitism.     

Career Concerns for People Living With HIV/AIDS

The purpose of this study was to identify the career concerns of people living with HIV/AIDS. The authors used qualitative research methodology to ask participants to discuss the impact their diagnosis has had on their career development concerns and their career goals. Based on participants' interview responses, the authors classified their concerns as relating to career or workplace issues, medical issues, or coping resources. Career counseling implications for each category are discussed.

The relationship between social support and psychological distress among Hispanic elders in Miami, Florida

This study compared 5 psychological models of the relationship between social support (SS) and behavioral health. These theoretical models, which have garnered some level of prior empirical support, were as follows: (a) main effects, (b) buffering effects, (c) social exchange, (d) equity, and (e) protective health outcomes of providing SS. A population-based sample of 273 community-dwelling Hispanic elders drawn from East Little Havana, Florida (ages 70-100 years old; 86% Cuban) completed self-report measures of SS, financial strain, and psychological distress (PD). Hierarchical multiple regression analyses were used to test the competing SS models. Results indicated that satisfaction with received SS was, as specified in the main-effects model, associated with lower PD, whereas received SS was unexpectedly associated with heightened PD. Reciprocal exchanges of SS (equity model) or exchanges where Hispanic elders provided more SS than they received (protective health outcomes of providing SS model) were also associated with lower PD. The feasibility of a 6th model in which the effects of SS are contingent upon the elder's preexisting PD level is proposed. Limitations, implications, and directions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved).     

Enhanced neuronal excitability in rat CA1 pyramidal neurons following trace eyeblink conditioning acquisition is not due to alterations in I M

Previous work done by our laboratory has demonstrated a reduction of the post-burst afterhyperpolarization (AHP) and accommodation following trace eyeblink conditioning in rabbit CA1 pyramidal neurons. Our laboratory has also demonstrated a reduction in the AHP in rat CA1 pyramidal neurons following spatial learning. In the current study we have extended our findings in rabbits by showing a reduction in both the AHP and accommodation in F344 X BN rat CA1 pyramidal neurons following acquisition of trace eyeblink conditioning. A component current of the AHP, I(M), was evaluated with a specific blocker of this current, and showed no apparent contribution to the learning-related increase in neuronal excitability. Rather, a reduction in an isoproterenol-sensitive component of the AHP, presumably sI(AHP), was observed to underlie the learning-specific change.     

Validation of the Preschool Anxiety Scale-Traditional Chinese (PAS-TC) in Hong Kong

Anxiety disorders are the most common type of psychiatric conditions in children. Early identification and intervention during preschool years is critical for minimizing their detrimental long-term effects. The Preschool Anxiety Scale (PAS) is a developmentally-sensitive and symptom-specific instrument that has been commonly used and widely validated in the west. The current study tested the psychometric properties of its Traditional Chinese version (PAS-TC) in Hong Kong. The study sample consisted of a total of 1317 Hong Kong parents, recruited from 12 local preschools, with preschool children aged from three to six years old. Results showed that a correlated five-factor model demonstrated a good fit for the data. PAS-TC also demonstrated acceptable reliability and satisfactory validity. Furthermore, gender but not age effects were found in Hong Kong. Additionally, similar to previous studies, items from physical injury fears were the most reported in the top-ten frequently endorsed items. Finally, the anxiety level of our Hong Kong sample was found to be between the Mainland China and western countries. Clinical implications of the above findings concerning PAS-TC are discussed.

     

The roles of meaningfulness and prior knowledge in younger and older adults' memory performance

Meaningfulness and prior knowledge can have differing effects on both metamemory and memory performance. Personally relevant information may be deemed more meaningful, which often can serve as a mediating factor in memory performance. Additionally, information that is congruent with prior knowledge has been shown to be judged as easier to remember and often is better remembered. Both of these effects are most pronounced in older adults. The current study aimed to examine the impact of meaningfulness and prior knowledge on age‐related differences in metamemory (i.e., judgments of learning) and memory performance (i.e., recall and recognition) by manipulating subjective a priori familiarity and personal relevance using age‐relevant study materials (i.e., a student loan application and a Medicare application). Recall metamemory and recall performance results indicate that older adults, but not younger adults, were able to utilize meaningfulness and prior knowledge to boost memory performance.
