Auditory streaming and vertical localization: Interdependence of “what” and “where” decisions in audition

When a sequence of two tones is presented over headphones in an ascending or descending order of pitch, it is heard as correspondingly ascending or descending in space. The illusion of spatial change that accompanies pitch change can be induced onto a pair of noise bursts by presenting them in synchrony with the tones. When cues known to produce stream segregation are introduced, the perceived position of the noises is less influenced by the tones. Stream organization is seen to be implicated in the ability to separately localize concurrent sources of sound. This suggests that “what” and “where” decisions are highly interactive and that neurological evidence that suggests separate pathways for these decisions must be interpreted with caution.     

Children’s scale errors and object processing: Early evidence for cross-cultural differences

Scale errors are observed when young children make mistakes by attempting to put their bodies into miniature versions of everyday objects. Such errors have been argued to arise from children’s insufficient integration of size into their object representations. The current study investigated whether Japanese and UK children’s (18–24 months old, N = 80) visual exploration in a categorization task related to their scale error production. UK children who showed greater local processing made more scale errors, whereas Japanese children, who overall showed greater global processing, showed no such relationship. These results raise the possibility that children’s suppression of scale errors emerges not from attention to size per se, but from a critical integration of global (i.e., size) and local (i.e., object features) information during object processing, and provide evidence that this mechanism differs cross-culturally.     

Do McCollough effects provide evidence for global pattern processing?

Contingent color aftereffects (CAEs, or McCollough effects) were induced using two pairs of orthogonally related patterns (horizontal/vertical and concentric/radial) to determine whether the CAEs of the four patterns are independent. Tests using composite test patterns (like those employed by Emerson, Humphrey, & Dodwell, 1985) suggested independent aftereffects. However, tests using unitary patterns indicated additive or competing effects of the four patterns in regions where line orientations were similar, and tests isolating such regions showed clear interactions between the pattern aftereffects. The results fail to support the claim that global (rather than local) features of the patterns control these CAEs.     

Is there evidence for automatic processing of spatial and color attributes present in pictures and words?

The current experiment studies evidence for automatic processing of color and spatial dimensions present in matched pictures and words. Subjects studied four lists of either line drawings or matched words that varied in color (red or green) and position (left or right side), under one of four encoding conditions. Subjects were instructed to encode (1) only the item, (2) the item and its color, 13) the item and its position, or (4) the item and both color and position. All subjects participated in an unexpected final recognition task in which item recognition and recall for both attributes, regardless of original encoding instructions, we:re examined. Color memory appeared to be effortful for both pictures and words, as it was at chance level unless subjects were specifically instructed to encode the information. Position was most poorly recalled when subjects attended only to item information, but memory for this dimension was well above chance in all encoding conditions. The position of the line drawings was better recalled than the position of the words. The implications of these results for Hasher and Zacks’ (1979) model of automatic processes is discussed.     

Expression,indication and showing what’s within

This essay offers a constructive criticism of Part I of Davis’ Meaning, Expression and Thought. After a brief exposition, in Sect. 2, of the main points of the theory that will concern us, I raise a challenge in Sect. 3 for the characterization of expression that is so central to his program. I argue first of all that a sincere expression of a thought, feeling, or mood shows it. Yet attention to this fact reveals that it does not go without saying how it is possible to show such things as thoughts, feelings or moods; we need an account of how this is possible, and I offer a partial such account in Sect. 4. Second, much of the attraction of Davis’ program depends on its ability to explain how linguistic meaning can be arrived at without covertly presupposing linguistic conventions. This in turn depends, in Davis’ hands, upon the claim that it is possible to express any of a wide range of ideas in the absence of conventions. I argue in Sect. 5 that the account of showing at which we will by then have arrived makes clear that Davis needs, and lacks, an explanation of how it is possible to do this.

Walking or talking? Behavioral and neurophysiological correlates of action verb processing

Brain activity elicited by visually presented words was investigated using behavioral measures and current source densities calculated from high-resolution EEG recordings. Verbs referring to actions usually performed with different body parts were compared. Behavioral data indicated faster processing of verbs referring to actions performed with the face muscles and articulators (face-related words) compared to verbs referring to movements involving the lower half of the body (leg-related words). Significant topographical differences in brain activity elicited by verb types were found starting approximately 250 ms after word onset. Differences were seen at recording sites located over the motor strip and adjacent frontal cortex. At the vertex, close to the cortical representation of the leg, leg-related verbs (for example, to walk) produced strongest in-going currents, whereas for face-related verbs (for example, to talk) the most in-going activity was seen at more lateral electrodes placed over the left Sylvian fissure, close to the representation of the articulators. Thus, action words caused differential activation along the motor strip, with strongest in-going activity occurring close to the cortical representation of the body parts primarily used for carrying out the actions the verbs refer to. Topographically specific physiological signs of word processing started earlier for face-related words and lasted longer for verbs referring to leg movements. We conclude that verb types can differ in their processing speed and can elicit neurophysiological activity with different cortical topographies. These behavioral and physiological differences can be related to cognitive processes, in particular to lexical semantic access. Our results are consistent with associative theories postulating that words are organized in the brain as distributed cell assemblies whose cortical distributions reflect the words' meanings.     

Remembering “what” brings along “where” in visual working memory

Does a behavioral and anatomical division exist between spatial and object working memory? In this article, we explore this question by testing human participants in simple visual working memory tasks. We compared a condition in which there was no location change with conditions in which absolute location change and absolute plus relative location change were manipulated. The results showed that object memory was influenced by memory for relative but not for absolute location information. Furthermore, we demonstrated that relative space can be specified by a salient surrounding box or by distractor objects with no touching surfaces. Verbal memory was not influenced by any type of spatial information. Taken together, these results indicate that memory for “where” influences memory for “what.” We propose that there is an asymmetry in memory according to which object memory always contains location information.     

When and where do we apply what we learn? A taxonomy for far transfer

Despite a century's worth of research, arguments surrounding the question of whether far transfer occurs have made little progress toward resolution. The authors argue the reason for this confusion is a failure to specify various dimensions along which transfer can occur, resulting in comparisons of "apples and oranges." They provide a framework that describes 9 relevant dimensions and show that the literature can productively be classified along these dimensions, with each study situated at the intersection of various dimensions. Estimation of a single effect size for far transfer is misguided in view of this complexity. The past 100 years of research shows that evidence for transfer under some conditions is substantial, but critical conditions for many key questions are untested.     

Binding “what” and “where” in auditory working memory: An asymmetrical association between sound identity and sound location

Contrasting results in visual and auditory working memory studies suggest that the mechanisms of association between location and identity of stimuli depend on the sensory modality of the input. In this auditory study, we tested whether the association of two features both encoded in the “what” stream is different from the association between a “what” and a “where” feature. In an old–new recognition task, blindfolded participants were presented with sequences of sounds varying in timbre, pitch and location. They were required to judge if either the timbre, pitch or location of a single-probe stimulus was identical or different to the timbre, pitch or location of one of the sounds of the previous sequence. Only variations in one of the three features were relevant for the task, whereas the other two features could vary, with task-irrelevant changes. Results showed that task-irrelevant variations in the “what” features (either timbre or pitch) caused an impaired recognition of sound location and in the other task-relevant “what” feature, whereas changes in sound location did not affect the recognition of either one of the “what” features. We conclude that the identity of sounds is incidentally processed even when not required by the task, whereas sound location is not maintained when task irrelevant.     

A longitudinal and multi-method examination of interest–occupation congruence within and across time

Remarkably little research has addressed change and stability in person–environment fit across time. The objective of the current study was to address this gap in the literature by investigating Holland interest–occupation congruence across time for a sample of college alumni (N = 167) that were tracked during the first third of their professional career. Congruence was examined in all its complexity, including a repeated assessment of both occupations and interests, the use of objective (O*NET) and subjective (self-report) environment assessment methods, and adopting sophisticated congruence calculation methods (i.e., Euclidean distance and profile correlation). This resulted in a total of 12 interest–occupation comparisons within and across time that could be related to general and career specific well-being. The results first indicated moderate levels of stability in interests and occupations across the 15-year time interval, yet also with room for change. Congruence analyses indicated significant interest–occupation fit at the beginning of the career and 15 years later, with the magnitude of congruence slightly varying depending on which occupation assessment and which congruence method was used. Profile correlation congruence did not change over time in absolute terms and evidenced relative stability. Euclidean distance indices had little relative stability over time but did manifest some absolute changes in levels of congruence. Finally, job change moderated the association between interest–occupation congruence and life satisfaction in such a way that higher levels of satisfaction were reported only when little job change was present.     

New evidence for “closure” in perception

A new criterion of perceptual grouping (Gillam, 1972), namely, that contours appear to reverse together under conditions of depth ambiguity, was used to test for the reality of “closure” and explore the parameters determining its degree. It was found that contours which would form a closed space but for a linear gap were responded to as a unit to a degree which decreased monotonically with gap size. Neither “proximal” nor “distal” gap was found to be the sole determinant of closure. Several levels of processing appear to be involved.

     

Composites, compromises, and CHARM: what is the evidence for blend memory representations?

Metcalfe's (1990) distributed memory model simulates many misinformation effects by assuming representations that superimpose information from multiple sources. In the present article, two types of evidence are reviewed for such "blend" representations: composite recollections, including items from both the original and postevent sources (e.g., a previously seen intersection is remembered with a subsequently suggested stop sign), and compromise recollections, including features that cannot be exclusively associated with either source (e.g., a green car that was later suggested to be blue is remembered as bluish green). The considerable evidence for composite recollections provides little support for blend representations. Compromise recollections, though seemingly more persuasive, are both rare and interpretable without postulating blend representations. Speculation is made about potential findings that would support blend representations.     

Auditory processing and perceptual abilities of “organic” and “functional” stutterers

The present investigation was undertaken to determine whether significant differences in auditory processing and perceptual abilities exist between (1) stutterers as a supposedly homogeneous group when compared with controls, (2) two differentiated subgroups of stutterers, and (3) either of the stuttering subgroups when separately compared with controls. Dichotic listening and masking level difference (MLD) tasks were administered to the two groups of school-age stutterers and an age-matched nonstuttering control group. Stuttering subjects were differentiated into “organic” and “functional” subgroups on the basis of neuropsychological test performances. Organic stutterers performed significantly poorer than did controls on one MLD experimental condition. Functional stutterers performed more like control subjects than like organic stutterers.     

Homophonic context effects when naming Japanese kanji: evidence for processing costs?

The current study investigated the effects of phonologically related context pictures on the naming latencies of target words in Japanese and Chinese. Reading bare words in alphabetic languages has been shown to be rather immune to effects of context stimuli, even when these stimuli are presented in advance of the target word (e.g., Glaser & Düngelhoff, 1984 Glaser, W. R. and Düngelhoff, F. J. 1984. The time course of picture–word interference. Journal of Experimental Psychology: Human Perception and Performance, 10: 640–654. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Roelofs, 2003 Roelofs, A. 2003. Goal-referenced selection of verbal action: Modeling attentional control in the Stroop task. Psychological Review, 110: 88–125. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). However, recently, semantic context effects of distractor pictures on the naming latencies of Japanese kanji (but not Chinese hànzì) words have been observed (Verdonschot, La Heij, & Schiller, 2010 Verdonschot, R. G., La Heij, W. and Schiller, N. O. 2010. Semantic context effects when naming Japanese kanji, but not Chinese hànzì. Cognition, 115: 512–518. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). In the present study, we further investigated this issue using phonologically related (i.e., homophonic) context pictures when naming target words in either Chinese or Japanese. We found that pronouncing bare nouns in Japanese is sensitive to phonologically related context pictures, whereas this is not the case in Chinese. The difference between these two languages is attributed to processing costs caused by multiple pronunciations for Japanese kanji.     

Inequality in personality and temporal discounting across socioeconomic status? Assessing the evidence

Personality traits such as conscientiousness and impulsivity correlate with temporal discounting, the degree to which individuals discount the value of future relative to present rewards. These variables have, in turn, been hypothesized to relate to income inequality in the United States. A key but untested assumption of this hypothesis is that the association among these variables is distinct across socioeconomic classes. The purpose of the present research is to test that assumption. N = 1100 adults with annual income ranging from at or below the poverty line ($0–$20,000) to upper-middle class ($200,000+) completed personality measures and a measure of temporal discounting. The results of our preregistered analyses indicated a positive association of income with trait planfulness, and a negative association with trait impulsivity and one parameter of temporal discounting that captures a bias to prefer sooner rewards to a greater degree if they are delivered that day. Our results can inform psychological theories of inequality and a broader conversation about effective public policy.     

Clinician Perspectives of Diagnosis and Perceived Client Change in “Real World” Psychotherapy for Youth Emotional and Behavioral Disorders

We investigated the extent to which clinician-assigned diagnoses of emotional and behavioral disorders and clinicians’ perceptions of client change are consistent with structured measures of youth clinical functioning and parent/family characteristics within the context of usual care or “real world” psychotherapy. A total of 54 therapists from two publicly-funded youth outpatient mental health clinics and 128 youths and parents from the therapists’ combined caseloads were included in the study. Clinician-assigned diagnosis and youth and family demographics were collected at the initial visit, clinician-reported perceived client change was collected at 6-month follow-up, and structured measures of youth clinical functioning and parent/family characteristics were collected at both time points. Results indicate some overlap between clinician-assigned diagnosis, clinician-reported perceived client change, and structured measures of youth clinical functioning and parent/family characteristics after controlling for demographic factors. Results are discussed in terms of implications for the implementation of evidence-based practices in real world community settings.     

Letter transpositions within and across morphemic boundaries: Is there a cross-language difference?

Research on the impact of letter transpositions that arise across morpheme boundaries has yielded conflicting results. These results have led to the suggestion that a cross-linguistic difference may exist in the recognition of Spanish and English words. In two masked-priming experiments run on separate groups of Spanish and English speakers, we tested this hypothesis by comparing the impacts of primes with letter transpositions that arose within morphemes or across morpheme boundaries on the recognition of identical or near-identical Spanish–English cognate targets. The results showed transposed-letter benefits in both Spanish and English that were not modulated by the position of the transposed letter in the prime stimulus. Our findings therefore add to the growing body of literature suggesting that the transposed-letter benefit is not affected by the position of the transposed letters relative to the morpheme boundary, and they dispel previous suggestions that there might be a genuine difference in orthographic coding across the Spanish and English writing systems.     

Predicting performance times from deliberate practice hours for triathletes and swimmers: what, when, and where is practice important?

In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice.
