Curiosity and the pleasures of learning: Wanting and liking new information

This paper proposes a new theoretical model of curiosity that incorporates the neuroscience of “wanting” and “liking”, which are two systems hypothesised to underlie motivation and affective experience for a broad class of appetites. In developing the new model, the paper discusses empirical and theoretical limitations inherent to drive and optimal arousal theories of curiosity, and evaluates these models in relation to Litman and Jimerson's (2004) recently developed interest-deprivation (I/D) theory of curiosity. A detailed discussion of the I/D model and its relationship to the neuroscience of wanting and liking is provided, and an integrative I/D/wanting-liking model is proposed, with the aim of clarifying the complex nature of curiosity as an emotional-motivational state, and to shed light on the different ways in which acquiring knowledge can be pleasurable.     

Nations Beyond Nationalism∗

Different brain mechanisms seem to mediate wanting and liking for the same reward. This may have implications for the modular nature of mental processes, and for understanding addictions, compulsions, free will and other aspects of desire. A few wanting and liking phenomena are presented here, together with discussion of some of these implications.     

Epinephrine,Arousal, and Emotion: A New Look at Two-factor Theory

Ever since William James, psychologists of emotion have tended to view affective states as intrinsically conscious. We argue that nonconscious affect also exists, and focus specifically on the possibility of unconscious "liking". We present evidence that positive and negative affective reactions can be elicited subliminally, while a person is completely unaware of any affective reaction at all (in addition to being unaware of the causal stimulus). Despite the absence of any detectable subjective experience of emotion, subliminally induced unconscious "liking" can influence later consumption behaviour. We suggest that unconscious "liking" is mediated by specific subcortical brain systems, such as the nucleus accumbens and its connections. Ordinarily, conscious liking (feelings of pleasure) results from the interaction of separate brain systems of conscious awareness with those core processes of unconscious affect. But under some conditions, activity in brain systems mediating unconscious core "liking" may become decoupled from conscious awareness. The result is a genuinely unconscious emotion.     

Anhedonic symptoms of depression are linked to reduced motivation to obtain a reward

People with depression report reduced motivation to obtain a reward and reduced affective responses to reward. However, studies focusing on the relation between anhedonia and deficits in reward processing are scarce. Furthermore, studies investigating wanting through cardiovascular reactivity and liking through facial electromyography in human beings are also scarce. In this study, we used the Temporal Experience of Pleasure Scale score as a continuous predictor variable of anhedonia and we manipulated two within-person conditions (wanting vs. liking). Participants earned money if their performance on a memory task exceeded a particular standard. As expected, effort-related cardiovascular reactivity and self-reports during the anticipatory phase were lower for participants scoring high on anhedonia. Moreover, task performance outcomes were worse for highly anhedonic participants. However, the zygomaticus major muscle’s activity during the consummatory phase was unrelated to the anhedonia score. The present study underlines the importance of anhedonic symptoms, particularly in reduced anticipatory motivation to obtain a reward.     

Self produced and observed actions influence emotion: the roles of action fluency and eye gaze

Affective responses to objects can be influenced by cognitive processes such as perceptual fluency. Here we investigated whether the quality of motor interaction with an object influences affective response to the object. Participants grasped and moved objects using either a fluent action or a non-fluent action (avoiding an obstacle). Liking ratings were higher for objects in the fluent condition. Two further studies investigated whether the fluency of another person’s actions influences affective response. Observers watched movie clips of the motor actions described above, in conditions where the observed actor could be seen to be looking towards the grasped object, or where the actor’s head and gaze were not visible. Two results were observed: First, when the actor’s gaze cannot be seen, liking ratings of the objects are reduced. Second, action fluency of observed actions does influence liking ratings, but only when the actor’s gaze towards the object is visible. These findings provide supporting evidence for the important role of observed eye gaze in action simulation, and demonstrate that non-emotive actions can evoke empathic states in observers. This research was supported by Economic and Social Research Council grant RES-000-23-0429 awarded to S. P. Tipper and A. E. Hayes.     

Childless adults with higher secure attachment state have stronger parenting motivation

This study aimed to systematically examine the coherence in the motivation of parenting with the security attachment state of adults. A total of 228 childless participants (126 men, 102 women) first completed a self-report questionnaire including the State Adult Attachment Measure scale and the Interest in Infants questionnaire. They were then administered three laboratory-based tasks: a) liking, which measured the specific hedonic experience to infants' neutral faces; b) representational responding (actively seeking infants' neutral faces); and c) evoked responding (actively retaining images of infants' neutral faces). The results revealed that after controlling for gender, anxiety, and avoidance, security attachment state was associated with higher levels of interest in infants, assessed via verbal measures, and associated with liking and wanting (divided into representational and evoked responding) for infants' neutral faces. Moreover, infant faces elicited pleasure but not the sense of dominance or wanting in individuals with high avoidance attachment state. These results suggest that improving security attachment state may enhance motivation for parenting and improve the quality of parental caregiving.     

Let me count the ways in which I respect thee: does competence compensate or compromise lack of liking from the group?

Two studies examined the effects of competence‐based respect in relation to liking‐based respect from ingroup members. First, a pilot study confirmed the impact of competence feedback from ingroup members on affective and emotional reactions (membership esteem, feelings of pride and shame). The main studies orthogonally manipulated both liking‐ and competence‐based respect from other ingroup members in order to examine whether (high) competence‐based respect compensates for lack of liking, or compromises the subjective position in the group, on affective and emotional reactions to the feedback. Using a scenario methodology Study 1 produced no evidence for compensation, and indicated that liking was primary in this context. Study 2, using experimental groups, provided further evidence that those who were disliked by their fellow group members felt compromised by a favourable evaluation of their competence, while remaining committed to the group. These effects are related to the different properties and implications of competence and liking dimensions in group interaction. Copyright © 2005 John Wiley & Sons, Ltd.     

Face the food: Food plating with facial patterns influences appetite and event-related brain potentials

The presentation of visual food cues (e.g., food plating) can affect our appetite and leads to characteristic changes of early as well as late positivity in the electroencephalogram. The present event-related potential (ERP) study attempted to change ERPs and affective ratings for food pictures by rearranging the components of a depicted meal (conventional presentation) as a smiley or frowny. The images were presented to 68 women (mean age?=?24 years), who rated the wanting and liking of the meals. Compared to conventional food plating, smiley and frowny meals elicited enhanced amplitudes of the P200, P300, and late positive potential (LPP) in a large occipito-parietal cluster. Frowny meals were rated as less appetizing than conventional food presentations. The mentioned ERP components are concomitants of face configuration processing (P200), automatic attention/novelty detection (P300), and voluntary attention/assignment of emotional meaning (LPP). Thus, the combination of two affective cues (food, face) in one stimulus changed the activation in motivational circuits of the brain. Also, serving a meal as a frowny could help to regulate appetite.

     

Liking, Arousal Potential, and the Emotions Expressed by Music

Previous research indicates that the specific emotions expressed by stimuli may be closely associated with their pleasing and arousing qualities, and this parallels psychomusicological research on the relationship between these two stimulus qualities. In light of this, the present research contends that the emotions expressed by musical stimuli are associated with their pleasing and arousing qualities. Sixty subjects rated 32 musical excerpts on 11-point scales representing the expression of eight specific emotions. Statistical analyses showed that these emotion ratings were predictable on the basis of 60 additional subjects' ratings of each excerpt in terms of 'liking' and 'arousal potential'. This indicates that ratings of liking and arousal potential are essentially similar to ratings of the specific emotions expressed by musical stimuli. These results are discussed in terms of the relationship between liking and arousal potential, and the implications that this may have for research on affective processes.     

The effects of mortality salience on political preferences: The roles of charisma and political orientation

Research has shown that mortality salience (MS) heightens liking for certain political candidates. Yet the particular qualities that make candidates more appealing after MS has been subject to debate. This study tested three possibilities: MS increases liking for charismatic candidates independent of participants’ or candidates’ political orientation; MS increases liking for conservative candidates independent of participants’ or candidates’ political orientation; and MS increases liking only for charismatic candidates who support the individual’s pre-existing political orientation, whether liberal or conservative. Following a MS manipulation, liberal and conservative participants evaluated two hypothetical gubernatorial candidates who differed both in their political orientation and level of charisma. MS heightened liking of charismatic candidates who shared the perceiver’s political orientation, whether liberal or conservative. In contrast, MS reduced liking for uncharismatic and opposing-orientation candidates. Results thus indicated that MS heightens regard for same-political orientation charismatic candidates, rather than just any charismatic candidate or conservative candidates. Implications for the influence of death-related concerns on political preference are briefly discussed.     

The inherent reward of choice

Research suggests that the exercise of control is desirable and adaptive, but the precise mechanisms underlying the affective value of control are not well understood. The study reported here characterized the affective experience of personal control by examining the neural substrates recruited when individuals anticipate the opportunity to make a choice--in other words, when they anticipate the means for exercising control. We used an experimental paradigm that probed the value of having a choice. Participants reported liking cues that predicted a future opportunity to make a choice more than cues that predicted no choice. The anticipation of choice itself was associated with increased activity in corticostriatal regions, particularly the ventral striatum, involved in affective and motivational processes. This study is the first direct examination of the affective value of having the opportunity to choose. These findings have important implications for understanding the role of perception of control, and choice itself, in self-regulatory processes.     

Changes in liking as a function of the magnitude and affect of sequential evaluations

A study was conducted to test derivations from the gain-loss model of interpersonal attraction (Aronson & Linder, 1965). In brief, liking change was examined within negative-positive and positive-negative sequences that consisted of evaluations differing in magnitude. The results confirmed gain-loss derivations in both sequences where evaluations of minor importance were followed by evaluations of major importance (a negative-positive sequence induced increases in liking, a positive-negative sequence induced decreases in liking); supportive results were also found in one major-minor sequence. A major negative-minor positive sequence produced increases in liking but the major positive-minor negative sequence did not produce decreases in liking. The increase in liking in the former (−−/+) sequence was significantly greater than the decrease (or lack thereof) in the latter (++/−) sequence (t = 3.70). In addition, the final liking ratings showed that a positive-negative sequence induced greater liking than a negative-positive sequence (F = 7.30) rather than the reverse as the gain-loss model predicts. The results were discussed in terms of the limits they suggested for the gain-loss model.     

Unconscious affective reactions to masked happy versus angry faces influence consumption behavior and judgments of value

The authors explored three properties of basic, unconsciously triggered affective reactions: They can influence consequential behavior, they work without eliciting conscious feelings, and they interact with motivation. The authors investigated these properties by testing the influence of subliminally presented happy versus angry faces on pouring and consumption of beverage (Study 1), perception of beverage value (Study 2), and reports of conscious feelings (both studies). Consistent with incentive motivation theory, the impact of affective primes on beverage value and consumption was strongest for thirsty participants. Subliminal smiles caused thirsty participants to pour and consume more beverage (Study 1) and increased their willingness to pay and their wanting more beverage (Study 2). Subliminal frowns had the opposite effect. No feeling changes were observed, even in thirsty participants. The results suggest that basic affective reactions can be unconscious and interact with incentive motivation to influence assessment of value and behavior toward valenced objects.     

Unconscious Emotion

Abstract— Conscious feelings have traditionally been viewed as a central and necessary ingredient of emotion. Here we argue that emotion also can be genuinely unconscious. We describe evidence that positive and negative reactions can be elicited subliminally and remain inaccessible to introspection. Despite the absence of subjective feelings in such cases, subliminally induced affective reactions still influence people's preference judgments and even the amount of beverage they consume. This evidence is consistent with evolutionary considerations suggesting that systems underlying basic affective reactions originated prior to systems for conscious awareness. The idea of unconscious emotion is also supported by evidence from affective neuroscience indicating that subcortical brain systems underlie basic "liking" reactions. More research is needed to clarify the relations and differences between conscious and unconscious emotion, and their underlying mechanisms. However, even under the current state of knowledge, it appears that processes underlying conscious feelings can become decoupled from processes underlying emotional reactions, resulting in genuinely unconscious emotion.     

A dual process model of affective and instrumental implicit attitude,self-monitoring,and sedentary behavior

IntroductionA dual process model based upon the affect and health behavior framework was used to explain sedentary behavior, where affective and instrumental components of implicit attitude were measured. Extending dual process theory, we assessed the moderating role of self-monitoring on the effects of implicit attitude on behavior.MethodIn Study 1, 148 office workers completed measures of affective and instrumental implicit attitude and self-monitoring at baseline, followed by a measure of sedentary behavior one week later. We then replicated this study in 241 undergraduates, with the addition of measures of the theory of planned behavior at the initial time point to represent conscious pathways to behavior.ResultsIn both studies there was no direct effect of either form of implicit attitude on behavior. However, self-monitoring moderated the effect of affective implicit attitude such that affective implicit attitude was a significant correlate of sedentary behavior only in those low in self-monitoring. In Study 2, sedentary behavior was also associate with intention, and intention was in turn associated with explicit affective attitude, subjective norm, and perceived behavioral control. Self-monitoring was not associated with sedentary behavior, nor did it moderate the intention-behavior relationship.DiscussionFindings suggest sedentary behavior is a largely affect driven behavior. Further, both reasoned and automatic processes contribute to sedentary behavior, but automatic processes only make a significant contribution when individuals are not consistently monitoring their behavior.     

Ventromedial prefrontal-subcortical systems and the generation of affective meaning

The ventromedial prefrontal cortex (vmPFC) comprises a set of interconnected regions that integrate information from affective sensory and social cues, long-term memory, and representations of the 'self'. Alhough the vmPFC is implicated in a variety of seemingly disparate processes, these processes are organized around a common theme. The vmPFC is not necessary for affective responses per se, but is critical when affective responses are shaped by conceptual information about specific outcomes. The vmPFC thus functions as a hub that links concepts with brainstem systems capable of coordinating organism-wide emotional behavior, a process we describe in terms of the generation of affective meaning, and which could explain the common role played by the vmPFC in a range of experimental paradigms.     

The impact of personality on cognitive, behavioral, and affective political processes: the effects of need to evaluate

Need to evaluate (NE) is a personality trait that reflects a person's proclivity to create and hold attitudes; people high in NE are especially likely to form attitudes toward all sorts of objects. Using data from the 1998 National Election Survey Pilot and the 2000 National Election Survey, NE was shown to predict a variety of important attitude-relevant cognitive, behavioral, and affective political processes beyond simply holding attitudes: NE predicted how many evaluative beliefs about candidates a person held, the likelihood that a person would use party identification and issue stances to determine candidate preferences, the extent to which a person engaged in political activism, the likelihood that a person voted or intended to vote, the extent to which a person used the news media for gathering information, and the intensity of emotional reactions a person felt toward political candidates. Thus, NE appears to play a powerful role in shaping important political behavior, emotion, and cognition.     

Toward a general theory of motivation: Problems,challenges, opportunities,and the big picture

Motivation theories have tended to focus on specific motivations, leaving open the intellectually and scientifically challenging problem of how to construct a general theory of motivation. The requirements for such a theory are presented here. The primacy of motivation emphasizes that cognition, emotion, agency, and other psychological processes exist to serve motivation. Both state (impulses) and trait (basic drives) forms of motivation must be explained, and their relationship must be illuminated. Not all motivations are the same, and indeed it is necessary to explain how motivation evolved from the simple desires of simple animals into the complex, multifaceted forms of human motivation. Motivation responds to the local environment but may also adapt to it, such as when desires increase after satiation or diminish when satisfaction is chronically unavailable. Addiction may be a special case of motivation—but perhaps it is much less special or different than prevailing cultural stereotypes suggest. The relationship between liking and wanting, and the self-regulatory management of motivational conflict, also require explanation by an integrative theory.
