Emergent Goal-Anticipatory Gaze in Infants via Event-Predictive Learning and Inference

From about 7 months of age onward, infants start to reliably fixate the goal of an observed action, such as a grasp, before the action is complete. The available research has identified a variety of factors that influence such goal-anticipatory gaze shifts, including the experience with the shown action events and familiarity with the observed agents. However, the underlying cognitive processes are still heavily debated. We propose that our minds (i) tend to structure sensorimotor dynamics into probabilistic, generative event-predictive, and event boundary predictive models, and, meanwhile, (ii) choose actions with the objective to minimize predicted uncertainty. We implement this proposition by means of event-predictive learning and active inference. The implemented learning mechanism induces an inductive, event-predictive bias, thus developing schematic encodings of experienced events and event boundaries. The implemented active inference principle chooses actions by aiming at minimizing expected future uncertainty. We train our system on multiple object-manipulation events. As a result, the generation of goal-anticipatory gaze shifts emerges while learning about object manipulations: the model starts fixating the inferred goal already at the start of an observed event after having sampled some experience with possible events and when a familiar agent (i.e., a hand) is involved. Meanwhile, the model keeps reactively tracking an unfamiliar agent (i.e., a mechanical claw) that is performing the same movement. We qualitatively compare these modeling results to behavioral data of infants and conclude that event-predictive learning combined with active inference may be critical for eliciting goal-anticipatory gaze behavior in infants.

Public engagement with emerging infectious disease: The case of MRSA in Britain

As a route to providing a framework for elucidating the content of public thinking concerning emerging and re-emerging infectious diseases (EID), this article examines public engagement with methicillin-resistant Staphylococcus aureus (MRSA). It explores how British lay publics represent MRSA utilising a social representations framework. For this group, MRSA is associated primarily with dirty National Health Service (NHS) hospitals that have been neglected due to management culture having superseded the matron culture that dominated the putative golden age of the NHS. Furthermore, MRSA represents a transgression of the purpose of a hospital as a clean and curative institution. While this widely shared picture is accompanied by a strong sense of general concern, the respondents associate contracting MRSA with other identities, such as hospitalised, young and old people. These associations are linked to feelings of personal invulnerability. There is also blame of foreigners – especially cleaners and nurses – for MRSA's spread. Thus, the data corroborate a key pattern of response found in relation to myriad EID – that of othering. However, the identities associated with contracting MRSA are mutable; therefore, the threat cannot be distanced unequivocally. Beyond developing an understanding of the relationship between epidemics and identities, this article proposes a fitting theory with which to explore EID-related public thinking.     

Autobiographical Memory in Patients with Tinnitus

Studies on psychiatric patients have found that their memories of the past are often unspecific and overgeneral, but the extent to which this is the case for patients with somatic problems has so far only been examined in patients with chronic pain and in patients with diabetes. The present study investigated autobiographical memories in 19 tinnitus patients and 19 controls without tinnitus. Participants were administered the autobiographical memory test (AMT), the Controlled word association test, and self-report measures of depression, anxiety, and tinnitus distress. Compared to control participants, tinnitus patients had difficulty retrieving specific memories and showed longer retrieval latencies. Additionally, tinnitus patients had fewer specific memories to positive cue words. While AMT responses were associated with depression scores, the difference between controls and patients remained significant for positive cue words after controlling for depression scores. Results suggest that cognitive components should be an integral element of the psychological management of tinnitus. The use in future studies of experimental methods such as AMT in health psychology is encouraged.     

Evaluative conditioning depends on higher order encoding processes

Evaluative conditioning (EC) is commonly conceived as stimulus-driven associative learning. Here, we show that internally generated encoding activities mediate EC effects: Neutral conditioned stimuli (CS) faces were paired with positive and negative unconditioned stimuli (US) faces. Depending on the encoding task (Is CS a friend vs. enemy of US?), Experiment 1 yielded either normal EC effects (CS adopting US valence) or a reversal. This pattern was conditional on the degree to which encoding judgements affirmed friend or enemy encoding schemes. Experiments 2a and 2b replicated these findings with more clearly valenced US faces and controlling for demand effects. Experiment 3 demonstrated unconditional encoding effects when participants generated friend or enemy relations between CS and US faces. Explicitly stated friend or enemy relations in Experiment 4 left EC effects unaffected. Together, these findings testify to the importance of higher order cognitive processes in conditioning, much in line with recent evidence on the crucial role of conditioning awareness.     

A Tale of Two Cities: Predicting Homeless People's Uptake of Outreach Programs in London and New York

Two studies involved structured interviews with 203 homeless people to examine the impact of sociodemographic variables, prior behavior, and the theory of planned behavior (TPB) variables, attitudes, subjective norms, perceived behavioral control, and intention, on uptake of outreach services. Study 1 was conducted in London, and Study 2 involved a comparable sample in New York. In line with previous research, the psychological variables accounted for more variance than the sociodemographic variables, and there was no evidence that the effects of TPB variables were moderated by sociodemographics. In London intentions and behavior were most affected by perceived control and subjective norms. In New York they were most affected by perceived control and attitude. These differences may be attributable to different institutional structures and opportunities for service uptake in the two cities. Sensitivity of the TPB to social context and implications for intervention strategies are discussed in light of these differences.     

Culture modifies the operation of prime-to-behavior effects

Culture affects the extent to which people focus on other people or on the situation in drawing inferences. Building on recent research showing that perceptions of others and situations can mediate prime-to-behavior effects, we tested whether culture would modify both the mechanism and the outcome of primed constructs on behavior. Easterners and Westerners were primed with competitiveness or cooperativeness before playing a social dilemma game with an ambiguously or unambiguously competitive player. Results indicated that the primes had different effects on the social dilemma decisions of Easterners and Westerners and that these effects were due to the different consequences the primes had for Easterners' and Westerners' perceptions of the other player and construals of the situation.     

A two-process view of Facebook use and relatedness need-satisfaction: disconnection drives use, and connection rewards it

Does using Facebook help people to meet their relatedness needs? Study 1 shows that more frequent Facebook usage paradoxically correlates with more relatedness satisfaction (connection) and more relatedness dissatisfaction (disconnection). Study 2 supports a 2-process explanation of this finding, showing that disconnection motivates greater usage as a coping strategy, whereas connection results from greater usage. Study 3 examines the effects of depriving participants of Facebook use for 48 hr. Further supporting the 2-process view, connection decreased, but disconnection was unaffected during the deprivation period; however, those who became more disconnected during the deprivation period engaged in more Facebook use during a 2nd, unconstrained 48-hr period, whereas changes in connection did not predict later use. In Study 4, participants set a Facebook reduction goal; initial disconnection interfered with and predicted worse performance in this goal. Implications for theories of psychological needs, behavioral motives, and adaptive coping are considered.
