Exposure to behavioral regularities in everyday life predicts infants’ acquisition of mental state vocabulary

There are two broad views of children's theory of mind. The mentalist view is that it emerges in infancy and is possibly innate. The minimalist view is that it emerges more gradually in childhood and is heavily dependent on learning. According to minimalism, children initially understand behaviors rather than mental states, and they are assisted in doing so by recognizing repeating patterns in behavior. The regularities in behavior allow them to predict future behaviors, succeed on theory-of-mind tasks, acquire mental state words, and eventually, understand the mental states underlying behavior. The present study provided the first clear evidence for the plausibility of this view by fitting head cameras to 54 infants aged 6 to 25 months, and recording their view of the world in their daily lives. At 6 and 12 months, infants viewed an average of 146.5 repeated behaviors per hour, a rate consistent with approximately 560,000 repetitions in their first year, and with repetitions correlating with children's acquisition of mental state words, even after controlling for their general vocabulary and a range of variables indexing social interaction. We also recorded infants’ view of people searching or searching for and retrieving objects. These were 92 times less common and did not correlate with mental state vocabulary. Overall, the findings indicate that repeated behaviors provide a rich source of information for children that would readily allow them to recognize patterns in behavior and help them acquire mental state words, providing the first clear evidence for this claim of minimalism.

Research Highlights

• Six- to 25-month-olds wore head cameras to record home life from infants’ point-of-view and help adjudicate between nativist and minimalist views of theory-of-mind (ToM).
• Nativists say ToM is too early developing to enable learning, whereas minimalists say infants learn to predict behaviors from behavior patterns in environment.
• Consistent with minimalism, infants had an incredibly rich exposure (146.5/h, >560,000 in first year) to repeated behaviors (e.g., drinking from a cup repeatedly).
• Consistent with minimalism, more repeated behaviors correlated with infants’ mental state vocabulary, even after controlling for gender, age, searches witnessed and non-mental state vocabulary.

     

Emotional experiences in everyday life: A survey approach

As part of a telephone survey, respondents were asked to report the most recent situation that evoked strong emotional feelings in them and to describe the pattern of their reactions. The majority of the situations reported had evoked negative emotions. Most of the emotion-antecedent events are connected to relationships with family and friends or to work-related situations. Only happiness and anger are reported as relatively pure feeling states; most others are emotion blends, with anger/sadness and sadness/fear occurring most frequently. Facial expression changes as well as heart and muscle symptoms are reported as the most frequent reactions across all emotions, whereas other nonverbal and physiological reactions are more specific for particular emotions. By the use of factor analysis, response patterns across various components of emotional state, including affect control, are explored.The first author gratefully acknowledges support from the Stiftung Volkswagenwerk for a sabbatical leave to the University of California at Berkeley.     

Negative affects deriving from the behavioral approach system

Does the behavioral approach system (BAS) relate to the experience of any negative affects, or are all negative affects tied to the behavioral inhibition system (BIS)? In Study 1, self-reported Fun Seeking predicted reports of greater frustration and sadness after frustrative nonreward. In Study 2, self-reported Reward Responsiveness predicted reports of greater anger in response to scenarios. In Study 3, self-reported Drive predicted reports of greater anger after the terrorist attacks of September 11, 2001. In no case did BIS sensitivity contribute uniquely to these affects, though BIS predicted nervousness in Study 2 and fear in Study 3. Discussion focuses on the role of frustration and anger in effortful pursuit of goals and depressed affect in disengagement from goals.     

Adolescents born extremely preterm: behavioral outcomes and quality of life

Fifty-two extremely premature born and 54 full-term controls were assessed regarding behavioral outcomes, risk-taking and self-perceived quality of life. Behavioral outcomes were assessed with the Achenbach Youth Self Report; risk-taking was estimated regarding alcohol and nicotine use; self-perceived quality of life and future expectations were rated; and attention and hyperactivity problems were surveyed retrospectively with the Wender Utah Rating Scale. The prematurely born reported fewer problems than full-term born on the externalizing scale (delinquent behavior and aggressive behaviour); and they reported less alcohol consumption. No difference was observed between the two groups concerning nicotine use, views about quality of life and expectations for the future or in the retrospective assessment of attention and hyper-activity problems. Conclusively, the prematurely born adolescents described a quality of life and future expectations comparable to full-term born controls. They also reported fewer behavioral problems and less risk-taking behavior.     

Inadvertent plagiarism in everyday life

Inadvertent plagiarism is a source monitoring error described in laboratory studies. In the present study, the existence of this phenomenon in everyday life and the impact of a variable considered in laboratory (i.e. source similarity) were investigated. Two hundred and two participants were asked to remember an episode involving inadvertent plagiarism in the past, and to describe it. Results showed that inadvertent plagiarism occurs in real life conditions with respect to various types of activities. Moreover, source similarity had an impact on inadvertent plagiarism. In particular, same‐sex plagiarism occurred more often than opposite‐sex plagiarism. Copyright © 2005 John Wiley & Sons, Ltd.     

Age differences in prospective memory for everyday life intentions: A diary approach

The age benefit found in many naturalistic prospective memory (PM) tasks has been taken as evidence that PM performance in real life may be spared from aging. However, this conclusion lacks empirical confirmation. Hence, the aim of the present study was to examine possible age differences in the content of everyday PM intentions and their performance. Everyday PM was assessed in young and older adults using a diary approach. Results confirmed a general age benefit for real-life PM tasks. Importantly, this finding was qualified by revealing that the benefit only held true for specific types of intentions such as health and social intentions. Further, moderation analyses showed that the relationships between cognitive functioning and everyday PM were different for young and older adults. While better inhibition, short-term and long-term memory were related with successful PM performance in the young, this was not the case in the older adults. The present findings suggest that the age benefit found in naturalistic experimenter-given tasks extends to real-life PM performance, but may differ depending on the type of intention. Furthermore, cognitive functioning predicts performance in the young, but not in the older adults.     

Subjective probability and everyday life

Abstract.— Recent research on probability judgement indicates that people's ability to estimate probabilities is very limited. It is argued that people may lack the cognitive apparatus necessary for processing probabilistic information, in so far as probability judgements play an unimportant role in everyday life. When probability judgements occasionally are made in everyday life it is argued that they are not based on frequency data but on some more or less well grounded theory.

Emotional experience in everyday life across the adult life span

Age differences in emotional experience over the adult life span were explored, focusing on the frequency, intensity, complexity, and consistency of emotional experience in everyday life. One hundred eighty-four people, age 18 to 94 years, participated in an experience-sampling procedure in which emotions were recorded across a 1-week period. Age was unrelated to frequency of positive emotional experience. A curvilinear relationship best characterized negative emotional experience. Negative emotions declined in frequency until approximately age 60, at which point the decline ceased. Individual factor analyses computed for each participant revealed that age was associated with more differentiated emotional experience. In addition, periods of highly positive emotional experience were more likely to endure among older people and periods of highly negative emotional experience were less stable. Findings are interpreted within the theoretical framework of socioemotional selectivity theory.     

How the motor system handles nouns: a behavioral study

It is an open question whether the motor system is involved during understanding of concrete nouns, as it is for concrete verbs. To clarify this issue, we carried out a behavioral experiment using a go-no go paradigm with an early and delayed go-signal delivery. Italian nouns referring to concrete objects (hand-related or foot-related) and abstract entities served as stimuli. Right-handed participants read the stimuli and responded when the presented word was concrete using the left or right hand. At the early go-signal, slower right-hand responses were found for hand-related nouns compared to foot-related nouns. The opposite pattern was found for the left hand. These findings demonstrate an early lateralized modulation of the motor system during noun processing, most likely crucial for noun comprehension.     

Action and emotion in everyday life

This study of naturally occurring behaviour employed a "beeper technique" to investigate the actions carried out by 152 subjects in eight different groups, viz. adult students, employed students who were also parents, unemployed, art students, doctoral students, alcoholics, retired people and a control group. Actions were sampled for seven subsequent days, five times per day between 8 a.m. and 10 p.m. at randomly selected occasions. Each action was rated on a number of variables, shortly after it was sampled (median delay approximately 10 min). Some of the findings were: Time allocation corresponded well with national estimates. Being under situational control was highly aversive. Instrumental and consummatory orientations correlated positively. The background variables were, on the whole, only rather weakly related to action ratings, but it was found that women and retired persons tended to report a higher level of well-being.     

Creativity and mental health in everyday life

Abstract

The connection between mental health and creativity has traditionally been studied in terms of outstanding aesthetic‐professional creativity and mental illness. More interesting however, is the possible connection between “everyday “ creativity and mental health. Everyday creativity involves attacking day to day activities in a divergent way: It derives from a complex of cognitive, affective, personal, motivational, and social factors, and is characterized by openness, flexibility, autonomy, playfulness, humor willingness to take risks, and perseverance. These characteristics are also consistently emphasized in models of “normal”; personality growth, so that the possibility of promoting mental health arises by fostering creativity in day to day life. Several small studies described in this article give examples of how this might be done and the kinds of benefits which can result.     

Behavioral activation and inhibition in everyday life

Joint effects of daily events and dispositional sensitivities to cues of reward and punishment on daily positive affect (PA) and negative affect (NA) were examined in 3 diary studies. Study 1 showed that positive events were strongly related to PA but not NA, whereas negative events were strongly related to NA but not PA. Studies 2 and 3 examined how the dispositional sensitivities of independent appetitive and aversive motivational systems, the Behavioral Activation System (BAS) and the Behavioral Inhibition System (BIS), moderated these relationships. Participants in Study 2 with higher BAS sensitivity reported more PA on average; those with more sensitive BIS reported more NA. Also, BIS moderated reactions to negative events, such that higher BIS sensitivity magnified reactions to negative events. Study 3 replicated these findings and showed that BAS predisposed people to experience more positive events. Results demonstrate the value of distinguishing within-person and between-person effects to clarify the functionally independent processes by which dispositional sensitivities influence affect.     

Self-awareness and aversive experience in everyday life

One hundred and seven adults reported their activities, thoughts, and feelings at randomly designated intervals over seven days, resulting in more than 4,800 self-reports. The present investigation focused on the relation of self-awareness and voluntariness to the quality of experience. Results indicated that perceived voluntariness is associated with positive experience, while self-awareness is associated with lower affect, activation, and personal involvement, but only when the activity is felt to be voluntary. This conditional association between self-awareness and aversive experience is discussed as it relates to current theory on self-awareness and recent models of human motivation.     

Souvenirs: Magical objects in everyday life

This article considers the role of souvenirs within domestic spaces. Souvenirs are ambivalent objects; at the same time the very epitome of tourism kitsch and personal objects for which the owner holds significant affection. Rather than pre-framing these objects either as ‘touristic signifiers’ or as personal memory objects, this article reflects on the roles they take as material and embodied co-habitants in domestic space, living - and communicating – with their owners. Hence, this paper departs from ‘humanistic’ accounts of cohabiting people and things and instead attempts to put human and non-human agents on an equal footing. It does so, by discussing the ‘magical capabilities’ of everyday objects that enable these to enchant the lives of their human cohabitants; animating them with affects and emotions, feelings of remembrance, affection, appreciation and loss. By drawing inspiration from autoethnography and in particular its potentials for interrogating objects, the author explores the ‘souvenirish’ qualities of five homely objects; using this exploration to enter into a dialogue with objects as well as theories and studies of objects. Considering the many faces of the souvenir - as utility item, mediator, fetish, tuner and artwork - the article suggests an opening for more imaginative thinking and explorations of how we live with objects in everyday life.     

The experience of emotions in everyday life

Abstract

A total of 47 employed adults were asked to record, in structured diaries, details of four episodes of emotion from the set that we regard as basic (happiness, sadness, anger, fear, disgust) and also to note occurrences of other emotions not in this set. Subjects experienced an average of about one episode of consciously recognised emotion a day, and in rating intensities they said that 11% of episodes were as intense as they could imagine. Anger was the most frequent of the basic emotions, and disgust the least frequent. There were no significant differences in rates or intensities of basic emotions as a function of gender. We predicted 69% of these emotions correctly from the goal-relevant events that elicited them: happiness was typically caused by achievements, sadness by losses, anger by frustration, and fear by threat, but the causation of disgust was more difficult to identify. In 31% of episodes pairs of basic emotions occurred in mixtures. Positive emotions tended to help plans, while negative ones tended to hinder them.
