Judging egocentric distance on the ground: occlusion and surface integration

On the basis of the finding that a common and homogeneous ground surface is vital for accurate egocentric distance judgments (Sinai et al, 1998 Nature 395 497-500), we propose a sequential-surface-integration-process (SSIP) hypothesis to elucidate how the visual system constructs a representation of the ground-surface in the intermediate distance range. According to the SSIP hypothesis, a near ground-surface representation is formed from near depth cues, and is utilized as an anchor to integrate the more distant surfaces by using texture-gradient information as the depth cue. The SSIP hypothesis provides an explanation for the finding that egocentric distance judgment is underestimated when a texture boundary exists on the ground surface that commonly supports the observer and target. We tested the prediction that the fidelity of the visually represented ground-surface reference frame depends on how the visual system selects the surface information for integration. Specifically, if information is selected along a direct route between the observer and target where the ground surface is disrupted by an occluding object, the ground surface will be inaccurately represented. In experiments 1-3 we used a perceptual task and two different visually directed tasks to show that this leads to egocentric distance underestimation. Judgment is accurate however, when the observer selects the continuous ground information bypassing the occluding object (indirect route), as found in experiments 4 and 5 with a visually directed task. Altogether, our findings provide support for the SSIP hypothesis and reveal, surprisingly, that the phenomenal visual space is not unique but depends on how optic information is selected.     

Long-term memory for music: infants remember tempo and timbre

We show that infants' long-term memory representations for melodies are not just reduced to the structural features of relative pitches and durations, but contain surface or performance tempo- and timbre-specific information. Using a head turn preference procedure, we found that after a one week exposure to an old English folk song, infants preferred to listen to a novel folk song, indicating that they remembered the familiarized melody. However, if the tempo (25% faster or slower) or instrument timbre (harp vs. piano) of the familiarized melody was changed at test, infants showed no preference, indicating that they remembered the specific tempo and timbre of the melodies. The results are consistent with an exemplar-based model of memory in infancy rather than one in which structural features are extracted and performance features forgotten.     

Relationship Between Specific Adverse Life Events and Psychiatric Disorders

This study examines whether certain psychiatric disorders are associated more closely with adverse life events than other disorders are, and whether some adverse life events are associated with a specific group of disorders (e.g., depressive disorders), but not with other disorders (e.g., anxiety disorders). A probability sample of youth aged 9–17 at 4 sites is used (N = 1,285). Univariate and multivariate logistic regressions identify specific relationships between 25 adverse life events and 9 common child and adolescent psychiatric disorders, measured by the Diagnostic Interview Schedule for Children. Conduct Disorder, Oppositional Defiant Disorder, Major Depressive Disorder, and Dysthymia are significantly associated with many of the adverse life events examined, whereas Attention Deficit/Hyperactivity Disorder, Agoraphobia, and Social Phobia are related to very few. This study suggests that certain psychiatric disorders may be more closely associated with adverse life events than other psychiatric disorders are, and that some adverse life events seem to be related to specific types of disorders.     

American base‐rate neglect: It is not the math,but the context

We investigate cross‐cultural disparities in focalism bias through two studies of probability estimation. Using 60 American and 60 Chinese participants, Experiment 1 yields the standard finding that Americans manifest greater focalism bias by tending to neglect background probability base‐rates and to rely more heavily on obtained samples in estimating true probabilities, whereas Chinese participants show little tendency to ignore base‐rates. In Experiment 2, the phrasing of the probability‐estimation task is changed to bring base‐rates into the focus of the problem statement, again using a sample of 60 Americans and 60 Chinese. This allows us to test whether cross‐cultural differences result from a tendency to focus on the sample, and ignore ‘context’ (i.e., the background base‐rates), rather than simply a discrepancy in mathematical facility between the two groups. The results show far less base‐rate neglect for Americans, but essentially no change for Chinese (who always use base‐rate information, regardless of how presented). This outcome argues against the explanation that Americans are poorer Bayesians simply because they are weaker mathematicians. Implications are discussed.

Measurement invariance of the Phubbing Scale across 20 countries

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face-to-face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between genders. Data were collected in 20 countries: Belarus, Brazil, China, Croatia, Ecuador, India, Israel, Italy, Netherlands, Pakistan, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, Turkey, UK, Ukraine and USA. The mean age across the sample (N = 7696, 65.8% women, 34.2% men) was 25.32 years (SD = 9.50). The cross-cultural invariance of the scale was investigated using multigroup confirmatory factor analyses (MGCFA) as well as the invariance analyses. Additionally, data from each country were assessed individually via confirmatory factor analyses (CFAs). We obtained two factors, based on only eight of the items: (a) communication disturbances and (b) phone obsession. The 8 items Phubbing Scale.

Comparing eye movements during position tracking and identity tracking: No evidence for separate systems

There is an ongoing debate as to whether people track multiple moving objects in a serial fashion or with a parallel mechanism. One recent study compared eye movements when observers tracked identical objects (Multiple Object Tracking—MOT task) versus when they tracked the identities of different objects (Multiple Identity Tracking—MIT task). Distinct eye-movement patterns were found and attributed to two separate tracking systems. However, the same results could be caused by differences in the stimuli viewed during tracking. In the present study, object identities in the MIT task were invisible during tracking, so observers performed MOT and MIT tasks with identical stimuli. Observer were able to track either position and identity depending on the task. There was no difference in eye movements between position tracking and identity tracking. This result suggests that, while observers can use different eye-movement strategies in MOT and MIT, it is not necessary.     

Investigating whether maternal memory specificity is indirectly associated with child memory specificity through maternal reminiscing

Maternal reminiscing and remembering has a profound influence on the development of children’s autobiographical remembering skills. The current study investigated the relationships between maternal memory specificity, maternal reminiscing and child memory specificity. Participants consisted of 40 mother–child dyads. Children’s age ranged between 3.5 and 6 years. Mothers and children participated in individual assessments of autobiographical memory specificity. Dyads participated in a joint reminiscing task about three past emotional (happy, sad, stressful) events. A positive moderate association was found between maternal autobiographical memory specificity and child autobiographical memory specificity. Maternal autobiographical memory specificity was significantly correlated with mothers’ focus on the task, involvement and reciprocity, resolution of negative feelings, and structuring of narratives in the mother–child reminiscing task. Moderate positive associations were found between maternal focus and structuring and child memory specificity. There was no evidence to suggest maternal elaborative reminiscing style was significantly positively correlated with mother or child memory specificity. Finally, there was support for an indirect pathway between maternal memory specificity and child memory specificity through quality of support and guidance provided by the mother in maternal reminiscing. Theoretical and clinical implications are considered.
