My Recency,Our Primacy: How Social Connection Influences Evaluations of Sequences

Individuals have many life experiences (e.g., work and vacations) that consist of a series of interconnected episodes (i.e., temporal sequences). Assessments of such experiences are integral to daily life in that they facilitate future planning and behaviors for individuals. Therefore, these experiences often culminate in evaluations of their global affect. Past work has shown that retrospective, affective evaluations of these sequences generally exhibit an “end effect,” whereby a sequence's end intensity—but not its start intensity—is disproportionately weighted. Yet, researchers have largely investigated experiences that occur alone. In contrast, many real‐world experiences vary in their extent of social connection to others (e.g., working in an office with others versus alone in a cubicle). The present work fills this gap by showing the moderating role of social connection on how episodes are weighted in global affective ratings. Five studies involving two autobiographical experiences spanning several days each (workweek and spring break) and two brief simulated experiences show that high social connection leads to greater (lesser) weighting of the first (last) episode. To our knowledge, we are the first to demonstrate that these effects persist across different forms of social connection (i.e., interpersonal interaction versus semantic priming tasks) and are supported regardless of whether social connection occurs at encoding or retrieval of an experience.

Resolution of an impasse at a network meeting: Dialogical sequence analysis of the use of a shared formulation

The study describes the resolution of an impasse at a network meeting during clinical child neurological assessment procedure, analysed by dialogical sequence analysis (DSA) a micro-analytic method for analysing utterances. The two earlier studies of the project describe how a DSA-based case conceptualisation can be used to assess change in the dyadic interaction between neuropsychologist and parent. This study applies the same formulation to analyse group level interaction at the network meeting. The case of a four-year-old girl was selected from a database of videotaped and transcribed child neurological team assessment processes. A repetitive problematic pattern was clearly manifested between parents and the child. At an early stage of the assessment, the neuropsychologist formulated and shared with the parents a clinical formulation of the pattern, summarised as the controlling/coercive parents to the rebellious child. In the earlier studies, microanalysis using DSA confirmed the accuracy of the neuropsychologist’s initial formulation, which she had used in the encounters with the parents. This study traces how she made use of it to address a re-enactment of the problematic pattern, now between the parents and professionals at the network meeting. The analysis of the phases of the conflict resolution by using DSA suggests that the impasse represented a re-enactment of the role positions of coercion and rebelliousness. The use of the original formulation at the meeting helped the conflicting parties to reach an observing stance to the pattern and a more empathic attitude to each other. The micro-analytic methodology by DSA used in this study allows to show the therapeutic potential of the network meeting and also how the development of an empathic stance is manifested in the discourse content.     

Motor timing and the preparation for sequential actions

Motor timing is essential for performing self-initiated movement sequences. Here, we investigated how sequence rhythm, or the timing for co-ordinating movements within a sequence, contributes to action preparation, compared with other processes occurring during sequence planning. First, we recorded the readiness potential (RP) in a condition of complex sequence rhythm and in condition of high demand on the timing for sequence initiation. We found that sequence rhythm and sequence initiation are independent processes, with sequence initiation contributing to early RP. Second, we compared the RP recorded in a condition of complex sequence rhythm and in a condition of complex sequence order, in which a complex combination of finger sub-movements had to be correctly ordered within a sequence. We found that sequence rhythm and sequence order share common processes occurring late RP. We suggest that the preparation for movement involves independent processes devoted to different aspects of motor timing and sequencing.     

Increasing compliance with medical examination requests directed to children with autism: effects of a high-probability request procedure

The purpose of this study was to evaluate the effectiveness of a high-probability (high-p) request sequence as a means of increasing compliance with medical examination tasks. Participants were children who had been diagnosed with autism and who exhibited noncompliance during general medical examinations. The inclusion of the high-p request sequence effectively increased compliance with medical examination tasks. In addition, the procedure was efficient, could be implemented by parents and medical professionals, and did not involve aversive procedures.     

AN EVALUATION OF A PROGRESSIVE HIGH-PROBABILITY INSTRUCTIONAL SEQUENCE COMBINED WITH LOW-PROBABILITY DEMAND FADING IN THE TREATMENT OF FOOD SELECTIVITY

Few studies have examined the effects of the high‐probability instructional sequence in the treatment of food selectivity, and results of these studies have been mixed (e.g., Dawson et al., 2003 ; Patel et al., 2007 ). The present study extended previous research on the high‐probability instructional sequence by combining this procedure with low‐probability demand fading with 2 boys with autism (9 and 10 years old) who had a history of food selectivity and engaged in active food refusal behaviors when presented with novel foods. Response requirements were faded gradually from responses the child would tolerate (e.g., touching the food) to the final requirement of chewing and swallowing the food. The antecedent‐based intervention was implemented in the absence of escape extinction and was effective in increasing food consumption for both participants. Possible mechanisms responsible for the effectiveness of the intervention are discussed along with directions for future research.     

Evidence of automatic processing in sequence learning using process-dissociation

This paper proposes a way to apply process-dissociation to sequence learning in addition and extension to the approach used by Destrebecqz and Cleeremans (2001). Participants were trained on two sequences separated from each other by a short break. Following training, participants self-reported their knowledge of the sequences. A recognition test was then performed which required discrimination of two trained sequences, either under the instructions to call any sequence encountered in the experiment "old" (the inclusion condition), or only sequence fragments from one half of the experiment "old" (the exclusion condition). The recognition test elicited automatic and controlled process estimates using the process dissociation procedure, and suggested both processes were involved. Examining the underlying processes supporting performance may provide more information on the fundamental aspects of the implicit and explicit constructs than has been attainable through awareness testing.     

Generalized lessons about sequence learning from the study of the serial reaction time task

Over the last 20 years researchers have used the serial reaction time (SRT) task to investigate the nature of spatial sequence learning. They have used the task to identify the locus of spatial sequence learning, identify situations that enhance and those that impair learning, and identify the important cognitive processes that facilitate this type of learning. Although controversies remain, the SRT task has been integral in enhancing our understanding of implicit sequence learning. It is important, however, to ask what, if anything, the discoveries made using the SRT task tell us about implicit learning more generally. This review analyzes the state of the current spatial SRT sequence learning literature highlighting the stimulus-response rule hypothesis of sequence learning which we believe provides a unifying account of discrepant SRT data. It also challenges researchers to use the vast body of knowledge acquired with the SRT task to understand other implicit learning literatures too often ignored in the context of this particular task. This broad perspective will make it possible to identify congruences among data acquired using various different tasks that will allow us to generalize about the nature of implicit learning.     

4岁儿童对过去事件的自传式回忆的表述特征

本研究目的是考察4岁儿童的自传式回忆的表述特征。研究对象为76名4岁儿童(男25,女51),让他们在实验室中面对陌生实验员和另三名儿童讲述自己过生日的经历。对录像材料的编码分为四个维度:对事件回忆的逻辑顺序性、事件内容的丰富性、表述的主动性以及讲述时的身体姿态。结果表明:(1)儿童在对过去事件做自传式回忆时,在事件回忆的逻辑顺序性方面,能够独立地按照事件发生顺序回忆的儿童占36.8%。(2)在进行自传式回忆时,儿童每人平均说出1 7个事件,25个字。(3)4岁儿童在陌生情境中对过去事件进行自传式回忆的能力表现接近于正态分布。(4)4岁儿童自传式表达的主动性与顺序性及含字量之间,事件个数与含字量及顺序性之间,顺序性与体态之间均存在显著的正相关关系。     

Tracking transitional probabilities and segmenting auditory sequences are dissociable processes in adults and neonates

Since speech is a continuous stream with no systematic boundaries between words, how do pre-verbal infants manage to discover words? A proposed solution is that they might use the transitional probability between adjacent syllables, which drops at word boundaries. Here, we tested the limits of this mechanism by increasing the size of the word-unit to four syllables, and its automaticity by testing asleep neonates. Using markers of statistical learning in neonates’ EEG, compared to adult behavioral performances in the same task, we confirmed that statistical learning is automatic enough to be efficient even in sleeping neonates. We also revealed that: (1) Successfully tracking transition probabilities (TP) in a sequence is not sufficient to segment it. (2) Prosodic cues, as subtle as subliminal pauses, enable to recover words segmenting capacities. (3) Adults’ and neonates’ capacities to segment streams seem remarkably similar despite the difference of maturation and expertise. Finally, we observed that learning increased the overall similarity of neural responses across infants during exposure to the stream, providing a novel neural marker to monitor learning. Thus, from birth, infants are equipped with adult-like tools, allowing them to extract small coherent word-like units from auditory streams, based on the combination of statistical analyses and auditory parsing cues.

Research Highlights

• Successfully tracking transitional probabilities in a sequence is not always sufficient to segment it.
• Word segmentation solely based on transitional probability is limited to bi- or tri-syllabic elements.
• Prosodic cues, as subtle as subliminal pauses, enable to recover chunking capacities in sleeping neonates and awake adults for quadriplets.
