The influence of a scene preview on eye movement behavior in natural scenes

Rich contextual and semantic information can be extracted from only a brief presentation of a natural scene. This is presumed to be activated quickly enough to guide initial eye movements into a scene. However, early, short-latency eye movements in natural scenes have been shown to be dependent on the salience distribution across the image (Anderson, Ort, Kruijne, Meeter, & Donk, 2015). In the present work, we manipulated the salience distribution across a natural scene by changing the global contrast. We showed participants a brief real or nonsense preview of the scene and examined the time-course of eye movement guidance. A real preview decreased the latency and increased the amplitude of initial saccades into the image, suggesting that the preview allowed observers to obtain additional contextual information that would otherwise not be available. However, the preview did not completely override the initial tendency for short-latency saccades to be guided by the underlying salience distribution of the image. We discuss these findings in the context of oculomotor selection based on the integration of contextual information and low-level features in a natural scene.     

Caching at a distance: a cache protection strategy in Eurasian jays

A fundamental question about the complexity of corvid social cognition is whether behaviours exhibited when caching in front of potential pilferers represent specific attempts to prevent cache loss (cache protection hypothesis) or whether they are by-products of other behaviours (by-product hypothesis). Here, we demonstrate that Eurasian jays preferentially cache at a distance when observed by conspecifics. This preference for a ‘far’ location could be either a by-product of a general preference for caching at that specific location regardless of the risk of cache loss or a by-product of a general preference to be far away from conspecifics due to low intra-species tolerance. Critically, we found that neither by-product account explains the jays’ behaviour: the preference for the ‘far’ location was not shown when caching in private or when eating in front of a conspecific. In line with the cache protection hypothesis we found that jays preferred the distant location only when caching in front of a conspecific. Thus, it seems likely that for Eurasian jays, caching at a distance from an observer is a specific cache protection strategy.     

Rebound or Resignation: Developing a Predictive Model of Return to Subjective Wellbeing Set-Point

Though subjective wellbeing (SWB) is generally stable and consistent over time, it can fall below its set-point in response to adverse life events. However, deviations from set-point levels are usually only temporary, as homeostatic processes operate to return SWB to its normal state. Given that income and close interpersonal relationships have been proposed as powerful external resources that are coincident with higher SWB, access to these resources may be an important predictor of whether or not a person is likely to recover their SWB following a departure from their set-point. Under the guiding framework of SWB Homeostasis Theory, this study considers whether access to a higher income and a committed partner can predict whether people who score lower than normal for SWB at baseline will return to normal set-point levels of SWB (rebound) or remain below the normal range (resigned) at follow-up. Participants were 733 people (53.3 % female) from the Australian Unity Longitudinal Wellbeing Study who ranged in age from 20 to 92 years (M = 59.65 years; SD = 13.15). Logistic regression analyses revealed that participants’ demographic characteristics were poor predictors of whether they rebounded or resigned. Consistent with homeostasis theory, the extent of departure from the proposed normal SWB set-point at baseline was significantly associated with rebound or resignation at time 2. These findings have implications for the way that SWB measures can be used in professional practice to identify people who are particularly vulnerable to depression and to guide the provision of appropriate and effective therapeutic interventions.     

What is the harm in harmful conception? On threshold harms in non-identity cases

Has the time come to put to bed the concept of a harm threshold when discussing the ethics of reproductive decision making and the legal limits that should be placed upon it? In this commentary, we defend the claim that there exist good moral reasons, despite the conclusions of the non-identity problem, based on the interests of those we might create, to refrain from bringing to birth individuals whose lives are often described in the philosophical literature as ‘less than worth living’.     

Eurasian jays (Garrulus glandarius) conceal caches from onlookers

Animals that cache food risk having their stored food pilfered by conspecifics. Previous research has shown that a number of food-caching species of corvid use strategies that decrease the probability of conspecifics pilfering their caches. In this experiment, we investigated whether Eurasian jays (Garrulus glandarius) would choose between caching behind an opaque and caching behind a transparent barrier whilst being observed by a conspecific. If caching in out-of-sight locations is a strategy to prevent conspecifics from pilfering these caches, then the jays should place a greater proportion of caches behind the opaque barrier when being observed than when caching in private. In accordance with this prediction, jays cached a greater proportion of food behind the opaque barrier when they were observed than when they cached in private. These results suggest that Eurasian jays may opt to cache in out-of-view locations to reduce the likelihood of conspecifics pilfering their caches.     

When Trust Fails: The Relation Between Children’s Trust Beliefs in Peers and their Peer Interactions in a Natural Setting

One hundred and forty-nine 8–11 year-old children (86 males; M?=?9 years - 4 months and SD?=?7 months) from the UK were administered the Trust Beliefs in Peers scale and were observed in the playground over one school year. Quadratic relations were found between trust beliefs in peers and peer interaction, which varied by gender. Compared to girls with the middle range of trust beliefs, girls with very low beliefs and those with very high beliefs (a) were less accepted/more rejected by the peer group (i.e., lower group interaction, and greater negatively received bids), (b) showed greater indirect aggression (engaged in and received), (c) showed greater non-engagement (i.e., being alone), and (d) showed greater concomitant distress. Compared to children with the middle range of trust beliefs, children with those extreme trust beliefs in peers demonstrated greater direct aggression (engaged in and received) and showed passive behavior (for boys only). The findings supported the conclusion that children, primarily girls, who trust peers too little and those who trust too much are at risk for psychosocial maladjustment.     

“It's Only Other People Who Make Me Feel Black”: Acculturation,Identity, and Agency in a Multicultural Community

This article explores identity work and acculturation work in the lives of British mixed‐heritage children and adults. Children, teenagers, and parents with mixed heritage participated in a community arts project that invited them to deliberate, construct, and reconstruct their cultural identities and cultural relations. We found that acculturation, cultural and raced identities, are constructed through a series of oppositional themes: cultural maintenance versus cultural contact; identity as inclusion versus identity as exclusion; institutionalized ideologies versus agency. The findings point towards an understanding of acculturation as a dynamic, situated, and multifaceted process: acculturation in movement. To investigate this, we argue that acculturation research needs to develop a more dynamic and situated approach to the study of identity, representation, and culture. The article concludes with a discussion on the need for political psychologists to develop methods attuned to the tensions and politics of acculturation that are capable of highlighting the possibilities for resistance and social change.     

FLEXING THE FRAME: CONTEMPLATING THE USE OF MULTIPLE PORTS OF ENTRY IN PARENT–INFANT PSYCHOTHERAPY

Multirelational interventions are well described in the psychoanalytic parent–infant literature. Daniel Stern (1995) originally suggested and described five “ports of entry” that may be employed to access the multiperson parent–infant clinical system. Other authors have elaborated and extended Stern's original list of ports of entry. The impact of using multiple ports of entry on the psychoanalytic frame, however, is largely neglected in the parent–infant psychotherapy literature. Danielle Quinodoz's (1992) four facets of the psychoanalytic setting are used to structure a discussion of how the multiplicities associated with parent–infant psychotherapy may impact the frame. The article argues strongly for a necessary flexing of the psychoanalytic frame to establish therapeutic alliances. A fifth facet, that of psychoanalytic mindfulness, is offered as a counterbalance to the risks associated with excessive flexing of the frame, particularly in relation to Quinodoz's fourth facet of “refraining from ‘doing.’” This article relies on case material to illustrate the issues under discussion. Further engagement and debate are invited.     

Throwing in the dark: improved prediction of action outcomes following motor training without vision of the action

Traditional models of action understanding emphasise the idea that long-term exposure to a wide array of visual patterns of particular actions allows for effective action anticipation or prediction. More recently, a greater emphasis has been placed on the motor system’s role in the perceptual understanding and prediction of action outcomes. There have been attempts to isolate the contributions of visual and motor experience in action prediction, but to date, these studies have relied on comparisons of motor-visual experience to visual-only (observational) experience. We conducted a learning study, where visual experience was directly manipulated during practice. Novice participants practised throwing darts to 3 specific areas of a dartboard. A group trained without vision of their action, only feedback about the final landing position, significantly improved in their ability to predict the landing position of a thrown dart, from temporally occluded video clips. The performance of this ‘no-vision’ group did not differ from a Full-vision group and was significantly more accurate than an observation-only and a no-practice control group (with the latter two groups not improving pre- to post-practice). These results suggest that motor experience specifically modulates the perceptual prediction of action outcomes. This is thought to occur through simulative mechanisms, whereby observed actions are mapped onto the observer’s own motor representations.
