Auditory statistical learning: predictive frequency information affects the deployment of contextually mediated attentional resources on perceptual tasks

Statistical learning is a general phenomenon in which environmental regularities are implicitly acquired through repeated exposure to those environments. Sometimes, that information can be utilised to affect various aspects of cognitive performance (e.g. reaction time) on tasks that utilise selective attention (e.g. visual search). In the current study, we examined the effect of passively listening to predictive auditory contexts in facilitating attention to a certain frequency or frequency range. In doing so, we found that there is a general tendency for attentional resources to be negatively affected when the context sequences are made novel after context–target associations have been formed (Experiment 1), and when the context no longer reliably cues the previous target (Experiment 2). The experiments are framed to contrast Associative Learning and Memory Hypothesis perspectives.     

Response Scatter in Measuring Changing-Loudness Aftereffects: Evidence for Simplified Processing of Auditory Motion-in-Depth and Potential Collision

Researchers have postulated 2 mechanisms for processing auditory motion: a direct mechanism processing motion itself and an indirect mechanism sensitive to location over discrete points in time. Measuring aftereffects of azimuthal motion by nulling entails scattered responding, which is attributed to a conflict between direct and indirect mechanisms. In this experiment, the author obtained nulls following adaptation to changing sound level, a property of approaching or receding sound sources, and for nonadaptation. Test stimuli ranged in duration from 1.0 to 2.5 s. Longer test stimuli evinced reductions in both changing-loudness aftereffects and the associated response scatters. However, the latter matched the nonadaptation response scatters. The author suggests that judging longer test stimuli is easier, so an indirect mechanism need not be invoked. Simplified processing of changing sound level may underlie the rapid responses required for potential collision.     

Modality effects in memory for basic stimulus attributes: A temporal and nontemporal comparison

Previous research suggests that there are significant differences in the operation of reference memory for stimuli of different modalities, with visual temporal entries appearing to be more durable than auditory entries (Ogden, Wearden, & Jones, 2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010). Ogden et al. (2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2010. Are memories for duration modality specific?. Quarterly Journal of Experimental Psychology, 63: 65–80. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) demonstrated that when participants were required to store multiple auditory temporal standards over a period of delay there was significant systematic interference to the representation of the standard characterized by shifts in the location of peak responding. No such performance deterioration was observed when multiple visually presented durations were encoded and maintained. The current article explored whether this apparent modality-based difference in reference memory operation is unique to temporal stimuli or whether similar characteristics are also apparent when nontemporal stimuli are encoded and maintained. The modified temporal generalization method developed in Ogden et al. (2008) Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] was employed; however, standards and comparisons varied by pitch (auditory) and physical line length (visual) rather than duration. Pitch and line length generalization results indicated that increasing memory load led to more variable responding and reduced recognition of the standard; however, there was no systematic shift in the location of peak responding. Comparison of the results of this study with those of Ogden et al. (2008 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2008. The remembrance of times past: Interference in temporal reference memory. Journal of Experimental Psychology: Human Perception and Performance, 34: 1524–1544. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2010 Ogden, R. S., Wearden, J. H. and Jones, L. A. 2010. Are memories for duration modality specific?. Quarterly Journal of Experimental Psychology, 63: 65–80. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggests that although performance deterioration as a consequence of increases in memory load is common to auditory temporal and nontemporal stimuli and visual nontemporal stimuli, systematic interference is unique to auditory temporal processing.     

Attention and the multiple stages of multisensory integration: A review of audiovisual studies

Multisensory integration and crossmodal attention have a large impact on how we perceive the world. Therefore, it is important to know under what circumstances these processes take place and how they affect our performance. So far, no consensus has been reached on whether multisensory integration and crossmodal attention operate independently and whether they represent truly automatic processes. This review describes the constraints under which multisensory integration and crossmodal attention occur and in what brain areas these processes take place. Some studies suggest that multisensory integration and crossmodal attention take place in higher heteromodal brain areas, while others show the involvement of early sensory specific areas. Additionally, the current literature suggests that multisensory integration and attention interact depending on what processing level integration takes place. To shed light on this issue, different frameworks regarding the level at which multisensory interactions takes place are discussed. Finally, this review focuses on the question whether audiovisual interactions and crossmodal attention in particular are automatic processes. Recent studies suggest that this is not always the case. Overall, this review provides evidence for a parallel processing framework suggesting that both multisensory integration and attentional processes take place and can interact at multiple stages in the brain.     

The own-species face bias: A review of developmental and comparative data

Face recognition is characterized in part by biases resulting in enhanced perception and memory for individuals within frequently encountered groups and impaired recognition for individuals within uncommonly encountered groups. These biases are found across multiple categories and levels, including species, race, age, and gender (Scherf & Scott, 2012). At the highest level of categorization, human adults and nonhuman primates exhibit improved recognition (Dufour, Pascalis, & Petit, 2006; Pascalis & Bachevalier, 1998) and discrimination abilities (Pascalis, de Haan, & Nelson, 2002) for individuals within their own species, reflecting what has been called an “own-species” or “species-specific” bias in face processing. The own-species bias is a model system for delineating the role of experience and the developmental trajectory of face-processing biases, for further understanding the malleability of face biases in adults, and for examining and comparing face-processing abilities across species. Here, we will review findings from studies investigating the perception of other-species faces during development, into adulthood and across species.     

婴儿对语音和非语音的感知:认知和神经机制

婴儿听觉感知能力的发展对于他们未来的语言学习和社会化都具有重要意义。过去大量的研究主要关注语音感知方面,只有较少的研究将非语音感知纳入考虑之中,但了解非语音感知的特征和机制将有助于增加研究者对听觉加工以及儿童发育的认识。该文分别介绍了婴儿语音感知中的三种偏好——对语音、“婴儿语”和母语的偏好,并尝试着将非语音分为音乐、人类的非言语发声、环境声音三类进行阐述。通过对比这两大类声音的感知得到婴儿可能存在语音感知的左脑偏侧化和音乐感知的右脑偏侧化现象,但这也尚存争议,目前有特定领域模型、特定线索模型和脑网络模型三种理论对偏侧化现象的认知机制进行解释。     

Familiar and unfamiliar face recognition: A review

Since the 1970s there has been a continuing interest in how people recognise familiar faces (Bruce, 1979 Bruce, V. 1979. Searching for politicians: An information processing approach to face recognition. Quarterly Journal of Experimental Psychology, 31: 373–395. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; Ellis, 1975 Ellis, H.D. 1975. Recognising faces. British Journal of Psychology, 66: 409–426. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). This work has complemented investigations of how unfamiliar faces are processed and the findings from these two strands of research have given rise to accounts that propose qualitatively different forms of representation for familiar and unfamiliar faces. Evidence to suggest that we process familiar and unfamiliar faces in different ways is available from cognitive neuropsychology, brain scanning, and psychophysics. However, in this review we focus on the evidence, available from experimental investigations of how people recognise faces, for different types of representation existing for each type of face. Factors affecting recognition are evaluated in terms of how they apply to familiar and unfamiliar faces and categorised according to the nature of their impact. In the final section this evidence, along with recent advances in the field, is used to explore the way in which unfamiliar faces may become familiar and the factors that may be important for the development of familiar face representations.     

The occurrence of the filled duration illusion: A comparison of the method of adjustment with the method of magnitude estimation

A time interval between the onset and the offset of a continuous sound (filled interval) is often perceived to be longer than a time interval between two successive brief sounds (empty interval) of the same physical duration. The present study examined whether and how this phenomenon, sometimes called the filled duration illusion (FDI), occurs for short time intervals (40–520 ms). The investigation was conducted with the method of adjustment (Experiment 1) and the method of magnitude estimation (Experiment 2). When the method of adjustment was used, the FDI did not appear for the majority of the participants, but it appeared clearly for some participants. In the latter case, the amount of the FDI increased as the interval duration lengthened. The FDI was more likely to occur with magnitude estimation than with the method of adjustment. The participants who showed clear FDI with one method did not necessarily show such clear FDI with the other method.     

A sub-process view of working memory capacity: Evidence from effects of speech on prose memory

In this article we outline a “sub-process view” of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion errors in WMC tasks. Since the sub-processes are functionally distinct, some sub-process may be related to a certain phenomenon, whereas another sub-process is related to other phenomena. In two experiments we show that a sub-process (measured by immediate/current-list intrusions) is related to the effects of speech on prose memory (semantic auditory distraction), whereas another sub-process (measured by delayed/prior-list intrusions), known for its contribution to reading comprehension, is not. In Experiment 2 we developed a new WMC task called “size-comparison span” and found that the relationship between WMC and semantic auditory distraction is actually a relationship with a sub-process measured by current-list intrusions in our new task.     

Perception,Memory, and Duration: The Binding Problem and the Synthesis of the Past

Theories of perception and of memory are closely allied. The binding problem (which considers how bits of perception are reassembled by the brain) leads to neurophysiological subjectivism. This could be outflanked by arguing with Bergson that perceiving consciousness is out in the world. Thus the brain would bind only behavioral “maps.” In turn, consciousness would retain our personal pasts. Such personal (episodic) memories both help us to recognize present objects and to perform creative acts. Memory, although retentive, is also creative. This is important in rethinking biological and evolutionary memory.     

Variable Perception of White Noise in Ambiguous Phonetic Contexts: The Case of /p/ and /f/

The roles of spectro-temporal coherence, lexical status, and word position in the perception of speech in acoustic signals containing a mixture of speech and nonspeech sounds were investigated. Stimuli consisted of nine (non)words in which either white noise was inserted only into the silent interval preceding and/or following the onset of vocalic transitions ambiguous between /p/ and /f/, or in which white noise overlaid the entire utterance. Ten listeners perceived 85% /f/s when noise was inserted only into the silent interval signaling a stop closure, 47% /f/s when noise overlaid the entire (non)words, and 1% in the control condition that contained no noise. Effects of spectro-temporal coherence seemed to have dominated perceptual outcomes, although the lexical status and position of the critical phoneme also appeared to affect responses. The results are explained more adequately by the theory of Auditory Scene Analysis than by the Motor Theory of Speech Perception.     

Establishing object correspondence across eye movements: Flexible use of spatiotemporal and surface feature information

Visual input is frequently disrupted by eye movements, blinks, and occlusion. The visual system must be able to establish correspondence between objects visible before and after a disruption. Current theories hold that correspondence is established solely on the basis of spatiotemporal information, with no contribution from surface features. In five experiments, we tested the relative contributions of spatiotemporal and surface feature information in establishing object correspondence across saccades. Participants generated a saccade to one of two objects, and the objects were shifted during the saccade so that the eyes landed between them, requiring a corrective saccade to fixate the target. To correct gaze to the appropriate object, correspondence must be established between the remembered saccade target and the target visible after the saccade. Target position and surface feature consistency were manipulated. Contrary to existing theories, surface features and spatiotemporal information both contributed to object correspondence, and the relative weighting of the two sources of information was governed by the demands of the task. These data argue against a special role for spatiotemporal information in object correspondence, indicating instead that the visual system can flexibly use multiple sources of relevant information.

Reliability and magnitude of auditory laterality effects: the influence of attention

Three experiments investigated the effect of attention on the reliability and magnitude of laterality effects in a dichotic listening task. In Experiment 1, 40 undergraduate students were randomly assigned to either a free-recall or focused-attention condition. In Experiment 2, 40 undergraduate students completed a dichotic listening task with exogenous cueing. They were randomly assigned to either a 150-ms stimulus onset asynchrony (SOA) or a 450-ms SOA condition. In Experiment 3, 20 participants completed a task where the SOA for the exogenous cue was randomized on a trial to trial basis. Results indicated that focused attention increased the magnitude of the laterality effect. Contrary to predictions, this finding was not due to reduced variability in the focused-attention task compared to the free-recall task. In addition, a cueing tone was only effective at directing attention in Experiment 3. Specifically, a significant right ear advantage observed at the 150-ms SOA was reduced at the 450-ms SOA. It appears that, in Experiment 3, the tone was effective at controlling attention because it reduced the systematic bias that has been suggested to account for the laterality effects observed in dichotic tasks.     

Sensitivity to amplitude envelope rise time in infancy and vocabulary development at 3 years: A significant relationship

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination of amplitude envelope rise times could be expected to relate to individual differences in language acquisition. A group of 50 infants taking part in a longitudinal study contributed rise time discrimination thresholds when aged 7 and 10 months, and their vocabulary development was measured at 3 years. Experimental measures of phonological sensitivity were also administered at 3 years. Linear mixed effect models taking rise time sensitivity as the dependent variable, and controlling for non‐verbal IQ, showed significant predictive effects for vocabulary at 3 years, but not for the phonological sensitivity measures. The significant longitudinal relationship between amplitude envelope rise time discrimination and vocabulary development suggests that early rise time discrimination abilities have an impact on speech processing by infants.     

The relationship between early life stress and working memory in adulthood: A systematic review and meta-analysis

ABSTRACT

Exposure to early life stress has been linked to impairment in cognitive functioning in adulthood. The aim of this study was to systematically review the literature on the relationship between early life stress and working memory, a central component of cognitive functioning. Database searches yielded 358 abstracts matching the search terms. Abstract screening followed by full-text review resulted in 26 publications suitable for inclusion, of which 23 were included in the meta-analysis. Results of the meta-analysis suggested exposure to early life stress was associated with poorer working memory. Even though there were a wide variety of working memory tasks used, this effect was significant for both phonological and visuospatial working memory tasks, and both visual and aural task presentation modalities. The effect was also found in samples with and without clinical psychopathology. This review provides recommendations for future research and implications for clinical practice.     

The psychological treatment of memory impairment: A review of empirical studies

Memory impairment is a frequent effect of many different forms of brain dysfunction. Memory impairment is also a frequent focus of treatment interventions, and there have been many different treatment methods suggested. The suggested methods include direct retraining, the use of spared skills in compensating for the impairment (alternate functional systems), and the use of behavioral strategies to circumvent the manifest memory dysfunction (behavioral prosthetics). Unfortunately, there are very few studies comparing the various suggested treatment methods. The present paper evaluates the empirical evidence related to the treatment of memory dysfunction and suggests directions for future investigations. Although the evidence is not conclusive, it appears that some forms of treatment may be helpful in remediating certain types of memory impairment. An approach likely to be productive would include some consideration of the impaired neurological and psychological mechanisms responsible for the manifest memory deficit as well as a consideration of the etiology of the injury thought to be causally related to the memory deficit. As yet, there have been no rigorous empirical evaluations of these considerations.     

Claiming hidden memories as one's own: A review of inadvertent plagiarism

Inadvertent plagiarism, or cryptomnesia, occurs when an individual claims another's idea as his or her own with no recollection of having been exposed to the idea before. Although some variation exists in the explanations of this occurrence, the source monitoring framework has emerged as the most plausible account. The purpose of this paper is to review the core body of research that has been conducted on cryptomnesia over the past two decades, with particular focus on the factors that affect the propensity of this phenomenon and how these influences inform a theoretical explanation of cryptomnesia. This paper also includes some suggestions for how future research might continue to explore the phenomenon of inadvertent plagiarism.
