Impulsivity as a predictor of smoking and alcohol consumption

This prospective study examined the relationships between impulsivity, smoking and alcohol use in a large non-clinical sample of 601 men and 4832 women working in 12 Finnish hospitals. Data on impulsivity, smoking and alcohol consumption were collected by two questionnaires with a two-year interval. At baseline, impulsivity was associated with smoking and alcohol use. After controlling for baseline smoking, impulsivity predicted increased number of cigarettes smoked per day in women (p=0.08), but not in men. After controlling for alcohol use at baseline, impulsivity predicted increased alcohol consumption similarly in both genders (p<0.01). Higher impulsivity was also associated with increased likelihood of taking up smoking or becoming a heavy drinker (p<0.05). This evidence suggests that impulsivity contributes to increasing health risk behaviours.     

Dear Santa,do you have my brand? A study of the brand requests,awareness and request styles at Christmas time

This study examines brand awareness (preferences) and request styles (communication approaches) at Christmas of Australian children and adults. The study is founded in the growing Santa Claus literature that has examined various issues related to gift giving and request behaviour at Christmas time. The study is based on the content analysis of 422 letters written by children to Santa Claus. The results indicate that children are brand‐orientated in their request behaviour, adopt fairly meaningful request strategies and use visual imagery ie graphics in their communication strategies in their attempts to secure their requested gifts and specific brands.

Impaired long-term potentiation and enhanced neuronal excitability in the amygdala of CaV1.3 knockout mice

Previously, we demonstrated that mice in which the gene for the L-type voltage-gated calcium channel Ca_V1.3 is deleted (Ca_V1.3 knockout mice) exhibit an impaired ability to consolidate contextually-conditioned fear. Given that this form of Pavlovian fear conditioning is critically dependent on the basolateral complex of the amygdala (BLA), we were interested in the mechanisms by which Ca_V1.3 contributes to BLA neurophysiology. In the present study, we used in vitro amygdala slices prepared from Ca_V1.3 knockout mice and wild-type littermates to explore the role of Ca_V1.3 in long-term potentiation (LTP) and intrinsic neuronal excitability in the BLA. We found that LTP in the lateral nucleus (LA) of the BLA, induced by high-frequency stimulation of the external capsule, was significantly reduced in Ca_V1.3 knockout mice. Additionally, we found that BLA principal neurons from Ca_V1.3 knockout mice were hyperexcitable, exhibiting significant increases in firing rates and decreased interspike intervals in response to prolonged somatic depolarization. This aberrant increase in neuronal excitability appears to be at least in part due to a concomitant reduction in the slow component of the post-burst afterhyperpolarization. Together, these results demonstrate altered neuronal function in the BLA of Ca_V1.3 knockout mice which may account for the impaired ability of these mice to consolidate contextually-conditioned fear.     

A diary study of implicit self-esteem, interpersonal interactions and alcohol consumption in college students

A 30-day daily diary study examined the relations among implicit self-esteem, interpersonal interactions, and alcohol consumption in college students. Multilevel analyses revealed that students with low implicit self-esteem drank more on days when they experienced more negative interpersonal interactions. In contrast, students with high implicit self-esteem drank more on days when they experienced more positive interpersonal interactions. Spending time with people who were drinking mediated both the low implicit self-esteem by negative interpersonal events interaction and the high implicit self-esteem by positive interpersonal events interaction. These findings suggest that people with low implicit self-esteem may unintentionally drink as a way to regulate unfulfilled needs for acceptance. On the other hand, people with high implicit self-esteem may drink as a way to enhance positive interpersonal experiences.     

期望、体验和回忆: 当消费者不能从体验中学习

人们对消费体验的期望、回忆与真实体验时常发生分离, 而且人们很少从真实体验中得到学习。本研究认为原因之一是期望、体验和回忆三者基于不同的输入信息, 以及三者特殊的交互关系。本研究首先提出了一个关于消费者期望、体验和回忆的理论框架, 系统阐述了消费者何时不能从体验中学习以及如何能促进学习, 然后在一个消费情景中通过3×2混合实验设计考察了三者的关系。实验比较了在“预期(无体验)”、“体验后即时评价”和“体验后延迟评价”三种评价方式下被试对两种品牌火腿肠的口味评价和偏好选择。结果发现: 消费者对口味体验的期望和回忆相似, 但两者都和真实体验发生分离。最后, 本研究还讨论了这一理论框架在消费者行为中的应用、未来研究拓展等。     

The effect of conspicuous consumption on men’s testosterone levels

Using evolutionary psychology as a theoretical framework, it is argued that conspicuous consumption serves as a means by which men communicate their social status to prospective mates. Accordingly, men’s endocrinological responses, particularly their testosterone levels, are responsive to fluctuations in their status as triggered by acts of conspicuous consumption. Study 1 reports that men’s testosterone levels increased and decreased partially (directionally), after driving an expensive sports car and an old family sedan, respectively. Additionally, the location of the drive, either a busy downtown area or a semi-deserted highway, partially moderated this response. Study 2 demonstrates that when men’s social status was threatened by the wealth displays of a male confederate in the presence of a female moderator, their testosterone levels increased. This is suggestive of an evolved mechanism for responding to intra-sexual challenges. Collectively, these constitute the first set of studies to measure hormonal outcomes in consumer behavior.     

环境消费心理学

环境消费心理学是近年来发展起来的一个分支。生态既是人类生存的基础 ,又是人类消费的对象。人们对环境问题的认知和个人的消费行为有很大的距离。环境问题的认知是很难和实际经验相联系的抽象概念。个人即使有保护环境的意识 ,在实际消费行为中往往选择与保护环境的态度不一致的行动。这是态度、认知和行为没有一致的产生原因。本文对环境和消费问题从社会心理学的角度进行了分析。     

Decreasing fuel-oil consumption through feedback and social commendation

The energy crisis of the winter of 1973-74 led to severe shortages of fuel oil for home heating and a government request for voluntary conservation by the oil consumer. This experiment tested two methods of facilitating fuel-oil conservation. Home fuel-oil consumers were randomly assigned to one of three experimental groups: feedback of information on rate of oil use, feedback plus commendation for reduced consumption, or a no-treatment control. The consumption rate for the feedback plus commendation group was significantly lower than that of either the informational feedback group or the control group. The informational feedback group did not differ from the control group. The results suggest that feedback alone may not result in oil conservation, but that feedback combined with commendation can produce socially significant savings.     

Associations between volume of alcohol consumption and social status, intelligence, and personality in a sample of young adult Danes

Relatively few studies have investigated associations between volume of alcohol consumption and psychological characteristics in normal samples. A sub-sample, comprising 363 men and 331 women between 29 and 34 years of age, was selected from the Copenhagen Perinatal Cohort on the basis of perinatal records. The sample was divided into four consumption categories: abstainers (including occasional drinkers), light, moderate, and risk drinkers. ANOVA and relevant contrasts were used to test the significance of differences among consumption categories. Both abstaining and risk drinking were associated with low social status family background, low education and intelligence. Abstaining was associated with low disinhibition and social recognition scores, while risk drinking was associated with high neuroticism and, in males, high disinhibition, low social recognition, and low achievement scores. Compared with light drinkers, a more "carefree" life orientation characterized male moderate drinkers, while relatively high scores on anxiety, dysthymia, and somatoform symptom scales characterized female moderate drinkers.     

Food and water intake as functions of resource consumption costs in a closed economy.

In two experiments, rats living in a closed economy were offered continuous, concurrent access to four resources: food, water, a nest, and a running wheel. Costs of consuming food and water were imposed with bar-press requirements, and the price of either one or both resources was raised. As the consumption cost increased, less was consumed in each bout of resource use. Bout frequency increased, but not sufficiently to compensate for the fall in bout size, and total intake fell. Food and water tended to be complementary resources, in that as intake of one fell with its price, intake of the other also decreased. This interaction was accounted for by the defense of the ratio of body water to lean body mass. As amount consumed decreased, increases in feed efficiency (weight gain per unit of food ingested) and the use of stored calories compensated for the reduced energy intake. There was evidence of competition between feeding and drinking at the higher costs: When both commodities were expensive, the decline in the intake of each one was greater than when only one commodity was expensive. Although the time spent nesting, running, and in unmonitored activity was adjusted when feeding or drinking took more of the rat's day, there was no particular activity that was sacrificed.
