Approach and avoidance as action effects

Numerous studies use arm movements (arm flexion and extension) to investigate the interaction between emotional stimuli and approach/avoidance behaviour. In many experiments, however, these arm movements are ambiguous. Arm flexion can be interpreted either as pulling (approach) or as withdrawing (avoidance). On the contrary, arm extension can be interpreted as reaching (approach) or as pushing (avoidance). This ambiguity can be resolved by regarding approach and avoidance as flexible action plans that are represented in terms of their effects. Approach actions reduce the distance between a stimulus and the self, whereas avoidance actions increase that distance. In this view, action effects are an integral part of the representation of an action. As a result, a neutral action can become an approach or avoidance reaction if it repeatedly results in decreasing or increasing the distance to a valenced stimulus. This hypothesis was tested in the current study. Participants responded to positive and negative words using key-presses. These “neutral” responses (not involving arm flexion or extension) were consistently followed by a stimulus movement toward or away from the participant. Responses to emotional words were faster when the response's effect was congruent with stimulus valence, suggesting that approach/avoidance actions are indeed defined in terms of their outcomes.     

Electrophysiological evidence for colour effects on the naming of colour diagnostic and noncolour diagnostic objects

In this study, we investigated the level of visual processing at which surface colour information improves the naming of colour diagnostic and noncolour diagnostic objects. Continuous electroencephalograms were recorded while participants performed a visual object naming task in which coloured and black-and-white versions of both types of objects were presented. The black-and-white and the colour presentations were compared in two groups of event-related potentials (ERPs): (1) The P1 and N1 components, indexing early visual processing; and (2) the N300 and N400 components, which index late visual processing. A colour effect was observed in the P1 and N1 components, for both colour and noncolour diagnostic objects. In addition, for colour diagnostic objects, a colour effect was observed in the N400 component. These results suggest that colour information is important for the naming of colour and noncolour diagnostic objects at different levels of visual processing. It thus appears that the visual system uses colour information, during naming of both object types, at early visual stages; however, for the colour diagnostic objects naming, colour information is also recruited during the late visual processing stages.     

A neurobehavioral investigation into judgmental processes: effect of bilateral motor behaviors

Two experiments were conducted in order to examine how different bilateral motor activations of the approach and avoidance motivational systems influenced participants' evaluations of valenced stimuli (figurative expressions and pictures of everyday situations). The first Study (Study 1) showed that participants judged valenced expressions according to the motor congruence model put forward by Cretenet and Dru (2004). This may depend on the compatibility of the valenced stimuli with the congruency of the bilateral motor behaviors that involved two unilateral motor behaviors that are congruent to each other. These results were duplicated in Study 2 with the use of valenced pictures taken from the International Affective Picture System. The overall results shed new light on the influence of motor behaviors on judgments, by determining the motor system as operative in evaluative mechanisms, and not merely a simple executive function of higher cognitive processes.     

Approach and avoidance motivation as predictors of pro-relationship behaviors

Pro-relationship behaviors, such as willingness to sacrifice, are assumed to be driven by both approach and avoidance motivation. However, this assumption has not been directly tested. In two studies, we examined how individual differences in approach and avoidance motivation predicted pro-relationship behavior. In Study 1, avoidance (but not approach) motivation uniquely predicted sacrificial behavior. In Study 2, sacrificing was uniquely predicted by avoidance motivation, whereas accommodation was uniquely predicted by approach motivation. These data suggest that although both sacrificing and accommodation are pro-relationship behaviors, they are driven by different motivational systems, which in turn may result in different long-term relational outcomes.     

Effects of valence and framing in decision-making: Assessing decision-makers' perceived domains of choice

Abstract: In comparison between choice alternatives, judgments of “How much better is a preferred option?” and “How much worse is a less preferred option?” may differ in their magnitudes. Such discrepancies are called “valence effects”. Previously, Yamagishi and Miyamoto (1996 ) observed systematic positive valence effects (“Better” exceeding “Worse”) in the domain of gains and systematic negative valence effects (“Worse” exceeding “Better”) in the domain of losses. The current experiments used the directions of valence effects as a tool to assess decision‐maker's interpretation of choice tasks under “framing effects” ( Tversky & Kahneman, 1986 ). Preferences under the framing effect switch from certain options in the domain of gains to uncertain options in the domain of losses. Two experiments showed that preferences for certain options were associated with positive valence effects, whereas preferences for uncertain options were associated with negative valence effects. Moreover, conditions wherein the framing manipulations lose the effectiveness were examined. Valence effects showed that framing effects ceased to occur when decision‐makers maintained consistent domain perceptions as pertaining to gains or to losses, across the domains of gains and losses. Implications are discussed.     

工作记忆中的积极效应：情绪效价与任务相关性的影响

积极效应指相比于年轻人, 老年人更倾向于优先加工积极情绪刺激而非消极情绪刺激。近年来工作记忆的研究发现积极效应会受到情绪效价与任务相关性的影响：情绪效价作为任务相关属性的研究支持工作记忆中存在积极效应, 具体表现为老年人对积极情绪刺激记忆的增强, 以及对消极情绪刺激记忆的减弱; 情绪效价作为工作记忆任务无关属性的研究相对较少, 且未发现一致的积极效应, 提示情绪效价及任务相关性均为影响工作记忆积极效应的关键因素。脑成像的研究初步表明, 工作记忆中情绪加工上的年龄效应与背侧执行系统和腹侧情绪系统的随龄功能变化有关。社会情绪选择理论与双竞争模型对工作记忆中的积极效应具备较大的解释力, 而动态整合理论尚缺乏实证研究支持。未来研究可进一步探究老年人工作记忆不同阶段情绪加工的特点, 澄清不同情绪材料内在编码过程上的差异对积极效应发生机制的潜在影响, 探讨情绪效价及任务相关性影响工作记忆积极效应的关键神经环路, 并揭示情绪工作记忆训练提升老年人认知功能与情绪体验的内在机制及其潜在应用价值。     

Independent effects of colour on object identification and memory

We examined the effects of colour on object identification and memory using a study–test priming procedure with a coloured-object decision task at test (i.e., deciding whether an object is correctly coloured). Objects were selected to have a single associated colour and were either correctly or incorrectly coloured. In addition, object shape and colour were either spatially integrated (i.e., colour fell on the object surface) or spatially separated (i.e., colour formed the background to the object). Transforming the colour of an object from study to test (e.g., from a yellow banana to a purple banana) reduced priming of response times, as compared to when the object was untransformed. This utilization of colour information in object memory was not contingent upon colour falling on the object surface or whether the resulting configuration was of a correctly or incorrectly coloured object. In addition, we observed independent effects of colour on response times, whereby coloured-object decisions were more efficient for correctly than for incorrectly coloured objects but only when colour fell on the object surface. These findings provide evidence for two distinct mechanisms of shape–colour binding in object processing.     

The effects of news report valence and linguistic labels on prejudice against social minorities

ABSTRACT

Combating prejudice against social minorities is a challenging task in current multicultural societies. Mass media can decisively shape prejudice, because it often represents the main source of information about social minorities. In 3 studies in the Czech Republic (N = 445) and Switzerland (N = 362; N = 220), we investigated how prejudice against negatively and positively perceived minorities (the Roma in Study 1, Kosovo Albanians in Study 2, Italians in Study 3) is influenced by a single exposure to a print news report, by manipulating the valence of reports about minority members (positive vs. negative vs. mixed) and linguistic forms for minorities’ ethnicity (nouns vs. adjectives). Positive and negative reports shaped prejudice in the respective directions; the effect of mixed reports mostly did not differ from positive reports. Labeling ethnicity with nouns (e.g., a male Roma) resulted in more prejudice than adjectives (e.g., a Roma man), independent of report valence. Report valence influenced the affective part of prejudice (i.e., feelings toward a minority), whereas language consistently shaped the behavioral part of prejudice (i.e., preferred social distance from a minority).     

Independent effects of word concreteness and word valence on immediate serial recall

The present study examined the roles of word concreteness and word valence in the immediate serial recall task. Emotion words (e.g. happy) were used to investigate these effects. Participants completed study-test trials with 7-item study lists consisting of positive or negative words with either high or low concreteness (Experiments 1 and 2) and neutral (i.e. non-emotion) words with either high or low concreteness (Experiment 2). In serial recall performance, we replicated the typical item concreteness effect (concrete words are better recalled than abstract words) and obtained an item valence effect (positive/neutral words are better recalled than negative words). However, there was no concreteness × valence interaction. We conclude that both word valence and word concreteness independently contribute to the serial order retention of emotion words in the immediate serial recall task.     

The effects of age and emotional valence on recognition memory: An ex‐Gaussian components analysis

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex‐Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex‐Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.     

A set of high quality colour images with Spanish norms for seven relevant psycholinguistic variables: The Nombela naming test

ABSTRACT

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.     

Physiological markers of challenge and threat mediate the effects of performance-based goals on performance

We predicted that adopting a performance-approach vs. performance-avoidance goal would lead to physiological responses characteristic of psychological states of challenge vs. threat appraisals, respectively. Furthermore, we predicted that these states would mediate the effects of goals on performance. Twenty-seven undergraduate females performed a task described as identifying either exceptionally strong performers (performance-approach goal) or exceptionally weak performers (performance-avoidance goal). Participants’ cardiovascular reactivity (CVR) was recorded while they performed the task. As predicted, participants in the performance-approach goal condition performed better on the task than did those in the performance-avoidance goal condition. Also as predicted, those in the former condition exhibited a challenge pattern of CVR whereas those in the latter condition exhibited a threat pattern of CVR. Furthermore, physiological responses mediated the effects of performance-based goals on performance.     

Perceptual and categorical judgements of colour similarity

Consideration is given to the tasks that make judgements of colour similarity based on perceptual similarity rather than categorical similarity. Irrespective of whether colour categories are taken to be universal (Berlin & Kay, 1969) or language induced (Davidoff, Davies, & Roberson, 1999), it is widely assumed that colour boundaries, and hence categorical similarity, would be used when categorising colours. However, we argue that categorical similarity is more reliably used in implicit than in explicit categorisation. Thus, in Experiment 1, we found that category boundaries may be overridden in the explicit task of matching-to-sample: There was a similar strong tendency to ignore colour boundaries and to divide the range of coloured stimuli into two equal groups in both Westerners and in a remote population (Himba). In Experiment 2, we showed that a distinctive stimulus (focal colour) in the range affected the equal division in a matching-to-sample task. Experiment 3 tested the stability of a category boundary in an implicit task (visual search) that assessed categorical perception; only for this task was categorisation largely immune to range effects and largely based on categorical similarity. It is concluded that, even after colour categories are acquired, perceptual rather than categorical similarity is commonly used in judgements of colour similarity.     

Reinforcement sensitivity theory as a predictor of senior-executive performance

This paper develops and tests links between the reinforcement sensitivity theory of personality and senior-executive job performance, hypothesising that the theory’s personality traits, known as ‘BIS’ and ‘BAS’, will interact to predict performance. 167 chief and second-tier executives completed Carver and White’s (1994)BIS/BAS Scales, and had their overall performance rated by a superior or peer using four items. Structural equation modeling showed that while BAS has no main effect and BIS has a marginally significant effect on performance (p = 0.07), BIS and BAS interact to predict performance (p = 0.01), the optimal scenario being a combination of high BAS and low BIS. These results show the importance of testing traits’ interactions in applied personality research.     

When inclusion hurts: The role of valence in moderating the effects of being in the loop

We explored conditions under which being in the loop may be an undesirable experience. We tested whether information valence moderates the effects of being in versus out of the loop in four studies. In a pilot study, participants imagined positive and negative events and indicated the degree to which they would like to know this information. In Study 1, participants imagined being in or out of the loop on positive or negative information and indicated how they would feel. In Study 2, participants relived an actual experience when they were in or out of the loop on positive or negative information. In Study 3, participants were in or out of the loop on positive or negative information needed for an upcoming task. These studies provide evidence that being in the loop on negative information can be an unenjoyable experience, threatening fundamental needs and increasing negative affect.     

The impact of valence framing on response expectancies of side effects and subsequent experiences: a randomised controlled trial

Abstract

Objective: Pre-treatment side effect expectancies often influence subsequent experiences; however, expectancy-based reduction strategies are lacking. We explored whether framing information about adverse responses (in positive or negative formats) altered expectancies and experiences of a cold pressor task. We further investigated associations between expectancies and experiences, to inform potential interventions.

Design: Healthy volunteers (N?=?134), randomised to receive positively- or negatively-framed pre-cold pressor task information, self-rated 12 expectancies for cold pressor experiences, emotional state and coping style.

Main Outcome Measures: Self-reports of the same 12-experiences (recorded during and after the experiment) were assessed.

Results: Framing had minimal impact on expectancies and experiences; however, discomfort threshold (p?=?.08, d?=?0.22) showed a trend in the expected direction. Hierarchical regressions revealed expectancies uniquely, significantly predicted 6–23% of the variance for 11 subsequent experiences. Following a popular charity event (Ice Bucket Challenge), all participants showed higher ‘discomfort thresholds’ (p?=?.001, d?=?0.59), and those in the negative frame reported more overall ‘discomfort’ (p?=?.01, d?=?0.60) than participants in the positive condition.

Conclusion: Expectancies uniquely influenced subsequent cold pressor experiences. Framing had minimal impact in this ‘analogue’ medical setting, only influencing ‘discomfort threshold’. ‘Discomfort threshold’ and overall ‘discomfort’ were also impacted by a social media challenge, highlighting a potential area for intervention.     

The news media and psychological distress

Abstract

The twentieth century has been marked by advances in communications technology as well as mounting psychological distress. This study explored the premise that exposure to negative news via the media contributes to anxiety and depression. Levels of news media exposure, stress levels, irrational beliefs, optimism-pessimism, anxiety, and depression were assessed (n=239) and analyzed using multiple regression techniques. Negative stress was directly related to anxiety and depression. News media exposure and anxiety were positively related at low levels of irrationality. News media exposure was predictive of trait anxiety at low levels of optimism. However, media exposure was not predictive of depression. The implications of the findings for understanding how the news media impacts stress and the cognitive factors that effect this relationship are discussed.     

The effect of neutral and negative colour photographs on children's item directed forgetting

Intentional forgetting is an active process relying on cognitive mechanisms (e.g., rehearsal strategies and inhibition) developing during the elementary school years. Colour photographs might be rehearsed differently in memory than words, and therefore result in a different developmental pattern of intentional forgetting than previously acknowledged. Moreover, negative material is thought to be particularly reliant upon inhibitory mechanisms in order not to be encoded in memory. Thus, children's item-directed forgetting (DF) might develop differently both in relation to colour photographs in general and for negative pictorial stimuli in particular. The aim of the present study was to investigate item DF for colour photographs of neutral and negative valence in sixty-five school-aged children (8–12 years of age). In the present study, a DF effect was revealed irrespective of age for neutral images as well as negative images. Results are discussed in relation to potential mechanisms underlying item DF for colour photographs and how these affect development of intentional forgetting.     

Direct evaluative conditioning in brand placement: The impact of scene valence and prominence on brand placement repetition effects

Whereas previous studies investigated the affect transfer from one specific affective stimulus of the brand placement context (such as an artist or the genre) to the brand, this research study investigates the effect of the valence of various scenes in which the brand is repeatedly placed on brand attitude. Direct evaluative conditioning theory suggests that pairing a brand repeatedly with various positive (negative) stimuli positively (negatively) affects brand attitude. The results of 2 experimental studies indicate that when a brand is repeatedly and prominently placed in different affective scenes of the same valence (a series of either positive or negative scenes), the affect aroused by those scenes influences explicit and implicit brand attitudes. In addition, whereas previous research found negative effects of brand prominence on brand evaluations, this study found that prominence positively moderates the affect transfer from the valence of various scenes on brand attitude. This implies that by placing the brand in various positive scenes, prominent brand placements can have a positive effect on recall and recognition and on brand attitude, which transcends the previously declared paradox of prominent placement.
