Gender and handedness effects on hedonicity of laterally presented odours

The effect of lateral presentation of odours on the hedonic evaluation is reported using a range of different substances. The hypothesis that hedonic evaluation of odours depends on stimulated nostril and on gender and handedness is tested using psychophysical methodology. A total of 51 untrained subjects evaluated 16 substances with different hedonic valences. Each odour substance was presented to the subjects four times, twice at each nostril using a balanced experimental design. Effects of gender and handedness, and interactions, are observed. Some parallels with the perception of visual emotional stimuli are suggested. Hedonic processing of odour stimuli is concluded to be an emotional, rather than an analytical task.     

Reaction in action: intergroup contrast in automatic behavior

Whereas previous research has shown automatic behavior conforming to outgroup stereotypes, the authors demonstrate automatic behavioral contrast away from a stereotype/trait associated with an outgroup (Study 1 and 2) and point to the importance of an "us-them" intergroup comparison in this process. In Study 1, participants colored pictures more messily when neatness was associated with an outgroup rather than the ingroup. In Study 2, using a different behavior, participants primed with busy business people reacted faster than controls (assimilation) but became slower when their student ingroup identity was activated (contrast). Subliminally priming an "us-them" intergroup comparison set undermined the accessibility of outgroup stereotypic words (Study 3), especially for those higher in prejudice (Study 4). This suggests that people automatically distance themselves from outgroup attributes when intergroup antagonism is cued or chronic. Implications for the role of self and comparison processes in automatic behavior are discussed.     

I like myself but I don't know why: enhancing implicit self-esteem by subliminal evaluative conditioning

On the basis of a conceptualization of implicit self-esteem as the implicit attitude toward the self, it was predicted that implicit self-esteem could be enhanced by subliminal evaluative conditioning. In 5 experiments, participants were repeatedly presented with trials in which the word I was paired with positive trait terms. Relative to control conditions, this procedure enhanced implicit self-esteem. The effects generalized across 3 measures of implicit self-esteem (Experiments 1-3). Furthermore, evaluative conditioning enhanced implicit self-esteem among people with low-temporal implicit self-esteem and among people with high-temporal implicit self-esteem (Experiment 4). In addition, it was shown that conditioning enhanced self-esteem to such an extent that it made participants insensitive to negative intelligence feedback (Experiments 5a and 5b). Various implications are discussed.     

When stereotypes get in the way: stereotypes obstruct stereotype-inconsistent trait inferences

There is a growing body of evidence indicating that people spontaneously make trait inferences while observing the behavior of others. The present article reports a series of 5 experiments that examined the influence of stereotypes on the spontaneous inference of traits. Results consistently showed weaker spontaneous trait inferences for stereotype-inconsistent behavioral information than for stereotype-consistent and stereotype-neutral information. Taken together, the current results suggest that specific spontaneous trait inferences become obstructed by inhibitory processes when behavior is inconsistent with an already activated stereotype. These findings are discussed in relation to stereotype maintenance processes and recent models of attribution in social judgment.     

Diversifying experiences enhance cognitive flexibility

Past research has linked creativity to unusual and unexpected experiences, such as early parental loss or living abroad. However, few studies have investigated the underlying cognitive processes. We propose that these experiences have in common a “diversifying” aspect and an active involvement, which together enhance cognitive flexibility (i.e., creative cognitive processing). In the first experiment, participants experienced complex unusual and unexpected events happening in a virtual reality. In the second experiment, participants were confronted with schema-violations. In both experiments, comparisons with various control groups showed that a diversifying experience – defined as the active (but not vicarious) involvement in an unusual event – increased cognitive flexibility more than active (or vicarious) involvement in normal experiences. Our findings bridge several lines of research and shed light on a basic cognitive mechanism responsible for creativity.     

To plan or not to plan? Goal achievement or interrupting the performance of mundane behaviors

The present experiment investigated cognitive and behavioral effects of planning (i.e. forming implementation intentions) on goal pursuit during the performance of mundane behaviors. Participants received the goal to collect a coupon halfway the hall from the lab to the cafeteria. Later, they were also given the task to go from the lab to the cafeteria. Thus participants had to attain a new goal by interrupting a mundane behavior. Some participants enriched their goal with implementation intentions, others did not. Results showed that participants who formed implementation intentions were more effective in goal pursuit than the control group. Importantly, the data suggest that the effects of planning on goal completion are mediated by a heightened mental accessibility of environmental cues related to the goal completion task.

The Unconscious Consumer: Effects of Environment on Consumer Behavior

In this article, we argue that consumer behavior is often strongly influenced by subtle environmental cues. Using grocery shopping as an example (or a “leitmotif,” if you wish), we first argue that the traditional perspective on consumer choice based on conscious information processing leaves much variance to be explained. Instead, we propose that many choices are made unconsciously and are strongly affected by the environment. Our argument is based on research on the perception–behavior link and on automatic goal pursuit.     

Where creativity resides: the generative power of unconscious thought

In three experiments, the relation between different modes of thought and the generation of "creative" and original ideas was investigated. Participants were asked to generate items according to a specific instruction (e.g., generate place names starting with an "A"). They either did so immediately after receiving the instruction, or after a few minutes of conscious thought, or after a few minutes of distraction during which "unconscious thought" was hypothesized to take place. Throughout the experiments, the items participants listed under "unconscious thought" conditions were more original. It was concluded that whereas conscious thought may be focused and convergent, unconscious thought may be more associative and divergent.     

Authority Defied: Need for Cognitive Closure Influences Regulatory Control When Resisting Authority

The present studies examined whether differences in need for cognitive closure (NCC) were related to differences in regulatory control when confronted with authority. In two studies, levels of regulatory control were measured when participants resisted (Study 1; N = 46) or prepared to resist the influence attempt of an authority figure (Study 2; N = 50). Results showed that resisting the influence attempt from a high‐authority figure was more depleting for participants higher in NCC compared to individuals lower in NCC. However, when they were given instructions and time to prepare the act of resistance, individuals high in NCC actually showed an increase in regulatory control. Authority is usually viewed as a general principle of influence; however, the present studies suggest that there are individual differences that influence how people may experience interactions with authorities.
