Infant responding to joint attention, executive processes, and self-regulation in preschool children

Infant joint attention is related to behavioral and social outcomes, as well as language in childhood. Recent research and theory suggests that the relations between joint attention and social-behavioral outcomes may reflect the role of executive self-regulatory processes in the development of joint attention. To test this hypothesis two studies were conducted. The first, cross-sectional study examined the development of responding to joint attention (RJA) skill in terms of increasing executive efficiency of responding between 9 and 18 months of age. The results indicated that development of RJA was characterized by a decreased latency to shift attention in following another person's gaze and head turn, as well as an increase in the proportion of correct RJA responses exhibited by older infants. The second study examined the longitudinal relations between 12-month measures of responding to joint attention and 36-month attention regulation in a delay of gratification task. The results indicated that responding to joint attention at 12-months was significantly related to children's use of three types of self-regulation behaviors while waiting for a snack reward at 36 months of age. These observations are discussed in light of a developmental theory of attention regulation and joint attention in infancy.     

Right‐Wing Authoritarianism: Protective Factor Against or Risk Factor for Depression?

Because the authoritarian personality was introduced to explain the rise of fascism during World War II, research focused on its ability to predict prejudice, leaving its associations with well‐being largely unexplored. Studies that did examine these associations yielded inconsistent results, and some authors even argued that authoritarianism buffers against the negative effects of psychological vulnerability factors (i.e. D‐type personality) and negative life events on well‐being, especially among people in an authoritarian environment. Using a cross‐sectional community sample (N = 1010), Study 1 failed to support the idea that authoritarianism relates to depressive symptoms and buffers against the negative effects of D‐type personality on depressive symptoms. Using a longitudinal college student sample (N = 499), Study 2 showed that authoritarianism did not moderate the effects of life events either and even predicted over‐time increases in depressive symptoms. Using a longitudinal high school sample (N = 590), Study 3 showed that this effect emerged regardless of degree of fit with the social environment (i.e. with family and friends). Taken together, results suggest that authoritarianism constitutes a risk factor for rather than a protective factor against depressive symptoms. Copyright © 2011 John Wiley & Sons, Ltd.     

Hypermaturity and Immaturity of Personality Profiles in Adolescents

Five‐year longitudinal data on a cohort of early to middle adolescents (N = 923) and a cohort of middle to late adolescents (N = 390) were used to examine the correlates of hypermaturity (i.e. 12‐year‐olds with a personality profile resembling the profile of an average 20‐year‐old) and immaturity (i.e. 20‐year‐olds with a personality profile resembling the profile of an average 12‐year‐old) of personality. Analyses revealed that girls with high levels of hypermaturity exhibited high levels of internalizing problem behaviour and conflict with parents, while hypermaturity in boys was only associated with internalizing problems. Immature girls had low levels of anxiety and high levels of minor delinquency, whereas immature boys reported low levels of anxiety and high levels of physical maturity. These findings suggest that off‐time personality development is an interesting concept deserving further exploration. Copyright © 2011 John Wiley & Sons, Ltd.     

Intrinsic and extrinsic contributions to heavy tails in visual foraging

Eyes move over visual scenes to gather visual information. Studies have found heavy-tailed distributions in measures of eye movements during visual search, which raises questions about whether these distributions are pervasive to eye movements, and whether they arise from intrinsic or extrinsic factors. Three different measures of eye movement trajectories were examined during visual foraging of complex images, and all three were found to exhibit heavy tails: Spatial clustering of eye movements followed a power law distribution, saccade length distributions were lognormally distributed, and the speeds of slow, small amplitude movements occurring during fixations followed a 1/f spectral power law relation. Images were varied to test whether the spatial clustering of visual scene information is responsible for heavy tails in eye movements. Spatial clustering of eye movements and saccade length distributions were found to vary with image type and task demands, but no such effects were found for eye movement speeds during fixations. Results showed that heavy-tailed distributions are general and intrinsic to visual foraging, but some of them become aligned with visual stimuli when required by task demands. The potentially adaptive value of heavy-tailed distributions in visual foraging is discussed.     

A computational-level explanation of the speed of goal inference

The ability to understand the goals that drive another person’s actions is an important social and cognitive skill. This is no trivial task, because any given action may in principle be explained by different possible goals (e.g., one may wave ones arm to hail a cab or to swat a mosquito). To select which goal best explains an observed action is a form of abduction. To explain how people perform such abductive inferences, Baker, Tenenbaum, and Saxe (2007) proposed a computational-level theory that formalizes goal inference as Bayesian inverse planning (BIP). It is known that general Bayesian inference–be it exact or approximate–is computationally intractable (NP-hard). As the time required for computationally intractable computations grows excessively fast when scaled from toy domains to the real world, it seems that such models cannot explain how humans can perform Bayesian inferences quickly in real world situations. In this paper we investigate how the BIP model can nevertheless explain how people are able to make goal inferences quickly. The approach that we propose builds on taking situational constraints explicitly into account in the computational-level model. We present a methodology for identifying situational constraints that render the model tractable. We discuss the implications of our findings and reflect on how the methodology can be applied to alternative models of goal inference and Bayesian models in general.     

Identity configurations across love and work in emerging adults in romantic relationships

Love and work constitute two life-defining identity domains for emerging adults. The present study utilized a five-dimensional identity model and examined identity configurations across these two domains, capturing the degree to which identity statuses correspond across domains. A sample of German 18–30-year-olds who were either working or studying and engaged in a romantic relationship was assessed at baseline and three years later. Six identity clusters emerged in each domain. Combining identity clusters across love and work domains, 7 identity configurations were distinguished. Whereas some configurations were characterized by strong commitments in one or both domains, other configurations consisted of individuals scoring low on commitment and high on exploration and rumination. These configurations were differentially related to psychological symptoms, work stress and satisfaction, and family–work conflict, both concurrently and longitudinally. Individuals characterized by high commitments in love and work provided the most favorable responses on all outcomes.     

In Defense of Relational Direct Realism

Abstract: According to proponents of relational direct realism, veridical perceptual experiences are irreducibly relational mental states that include as constituents perceived physical objects or intrinsic aspects of them. One consequence of the theory is the rejection of the causal theory of perception. This paper defends the relational theory against several objections recently developed by Paul Coates. He argues that the required experiential relation is incoherent and unmotivated. The argument that it is incoherent commits a fallacy. In reply to the argument that it is unmotivated, I suggest that the relational theorist's appeal to transparency provides sufficient motive and, when properly clarified, defeasibly justifies the theory as well. Coates also argues that rejection of the causal theory leaves relational theorists without any way of determining which object is perceived or of accommodating our scientific understanding of perceptual experiences as causally dependent on physical objects. I reply that relational theorists are able to provide the required explanations and discuss how the relational theory is consistent with this scientific understanding of perceptual experience.
