Strategies,context, and the mechanism of response inhibition

A series of four experiments investigated Neill’s 11977) claim that there are inhibitory mechanisms in selective attention. It was demonstrated that the evidence supporting the inhibitory theory, namely, the diminished availability of distractor responses during a discretetrials version of the Stroop task is complicated by a number of strategic adaptations to various contingencies within the trial sequence. These results do not support a simple interpretation of response inhibition during the Stroop task.     

Relationship of Maudsley Obsessional-Compulsive Inventory Subscales with Negative Priming

The relationship between the 4 subscales (Checking, Cleaning, Doubting, Slowness) and total score of the Maudsley Obsessional-Compulsive Inventory (MOCI) and performance in a negative-priming task and a response-speed task in 102 undergraduates was examined. Only Cleaning subscale performance correlated with magnitude of negative priming. Performance on the Checking, Slowing, and Doubting subscales was not significantly related to the magnitude of negative priming. The not significant correlation between Checking score and negative priming magnitude supports the findings of Maki, O'Neill, and O'Neill (1994), who observed that compulsive checking (of, e.g., whether the stove is turned off) appeared to be unrelated to deficiencies in inhibitory control. The present results are not, however, consistent with the view that obsessive-compulsive characteristics (as measured by the MOCI) result in a disruption in and a reduction of inhibitory control (Enright & Beech, 1993).     

On the time course of negative priming: Another look

In two experiments, the pattern of persistence of negative priming effects across delay intervals of 500 and 2,500 msec was assessed using a within-subjects, random sequencing of delays. Neill and Valdes (1992; Neill, Valdes, Terry, & Gorfein, 1992) have argued that a within-subject experimental design is required for decay of negative priming to be seen, in contrast to results reported elsewhere (e.g., Tipper, Weaver, Cameron, Brehaut, & Bastedo, 1991) showing stable negative priming effects across delays. In neither experiment was substantial evidence of decay detected, raising questions for the notion that suppression necessarily declines across brief temporal intervals and for the assertion that episodic retrieval is the sole source of negative priming.     

Negative priming and stimulus repetition: A reply to Neill and Joordens (2002)

Negative priming is reliably obtained with repeated items, but not with novel items. Here, we review why these stimulus repetition effects raise problems for memorybased theories of negative priming. Furthermore, we provide empirical evidence casting doubt on Neill and Joordens’s (2002) claim that perceptual facilitation masks the effects of episodic retrieval with novel items. Finally, we discuss several theoretical and methodological issues raised in the reply by Neill and Joordens. We conclude that a more straightforward interpretation of these stimulus repetition effects is one based on activation-sensitive inhibition.     

The time-course of negative priming: Little evidence for episodic trace retrieval

An episodic trace retrieval (ETR) explanation of negative priming (NP) predicts that the NP effect should be sensitive to the timing of delays between trials (Neill & Valdes, 1992; Neill, Valdes, Terry, & Gorfein, 1992). Specifically, according to ETR, (1) NP is affected by the response-stimulus interval (RSI) before the prime display, and (2) NP decays when RSI is manipulated within groups but not when RSI is manipulated between groups. Two localization tasks and two identification tasks are reported that question the reliability of these findings. The results suggest that there is little in the time-course literature that uniquely supports the ETR theory of NP. Instead, the results seem more compatible with either a dual-mechanism account (Kane, May, Hasher, Rahhal, & Stoltzfus, 1997) or an integrative approach that incorporates both memory and attention processes (Milliken, Joordens, Merikle, & Seiffert, 1998).     

On Vandervert et al. “Working Memory,Cerebellum, and Creativity”

Four measures of self-determination (SD) were correlated with two measures of trait creativity. In Study 1, subjects high on the Creative Personality Scale (Gough, 1979) and the Problem-Solving/Creativity scale (Marsh &; O'Neill, 1984) were found to strive for self-determined reasons, to strive toward greater SD, and to evidence higher SD in measures of both motivational orientation and self-concept. Study 2 replicated most of these findings and also showed that creative subjects perceived their parents to be more autonomy supportive. Results are interpreted in terms of a general disposition to be self-determining that may help attune creative people to deeper cognitive resources and capacities within themselves.     

O'NEILL'S JOURNEY

This paper considers some of the processes through which Eugene O'Neill (1888–1953) dramatically shaped his inner life and through which he created his plays. These processes at their finest are evident in his composition of Long Day's Journey into Night (1941a). During its 21‐month composition, the play went through three different versions, as evidenced by the playwright's handwritten and typed materials (O'Neill, unpublished, a, b, c, d). This paper posits that each version reflects O'Neill's changing state of mind as he began to master his instinctual life, developing increasingly rich characters and creating a painful, deeply tragic vision. Thus, this paper shows that O'Neill's great artistic achievement reflected a great psychological one.     

A Meta-Analysis of the Effects of Adventure Programming on Locus of Control

Adventure programs utilize the outdoors and/or activities to accomplish goals that are recreational, educational, enrichment or preventive oriented, or therapeutic. These programs encourage active manipulation of surroundings and the utilization of pro-active survival skills. In the growing field of Adventure Programming (and within the more specific field of Adventure Therapy), there exists a need to link valuable program characteristics to specific outcomes. Locus of control has been theorized to be a moderator of change in adventure programs, however past research has yielded inconsistent and contradicting results. An attempt was made to replicate the effect size of 0.30 generated within the comprehensive meta-analyses of both D. R. Cason (1993) and J. Hattie, H. W. Harsh, J. T. Neill, and G. E. Richards (1997). A slightly higher effect size of 0.38 was computed, substantiating evidence that subjects across studies became significantly more internal as a result of participation. Investigation of specific outcomes yielded two possible variables as moderators of locus of control effect size: program goal and daily duration.     

Negative priming from ignored distractors in visual selection: A review

Ignoring a distractor on a prime trial generally impairs responses to that object on a subsequent probe trial. This negative-priming (NP) effect supports the notion that distracting objects are actively inhibited during target selection (Tipper, 1985). Alternatively, NP may be caused either by amismatch between the features of items across prime and probe trials (Park & Kanwisher, 1994) or by the episodic retrieval of information from the prime trial which conflicts with the current, correct response (Neill & Valdes, 1992). These alternative accounts are called theselective inhibition,feature mismatching, andepisodic retrieval hypotheses, respectively. The present paper reviews the NP literature and considers the evidence for each of the three accounts. Feature mismatching does produce NP in a limited number of cases, but it is not a necessary condition for NP. In other cases, NP must be due to either selective inhibition or episodic retrieval of previously ignored distractors. Though results from critical tests designed to discriminate among these hypotheses have not yet been reported, such results are crucial for both theoretical and practical reasons.     

Onora O’Neill: <Emphasis Type="BoldItalic">Justice Across Boundaries: Whose Obligations?</Emphasis>

This review sets out the central arguments of Onora O’Neill’s book Justice Across Boundaries: Whose Obligations? and argues that whilst she puts forward a variety of incisive criticisms of the international human rights movement she fails to present any positive argument for improving it. Ultimately the book is an exceptional piece of criticism that lacks any significant attempt to solve the many problems that O'Neill highlighted.     

Clients As Change Agents: What Color Could My Parachute Be?

Morrill and Forrest (1970) advocate an approach to career counseling (Type 4) that helps clients (a) understand career choice as a developmental process, (b) learn decision-making skills, and (c) become active change agents in their own lives. Referring to the Morrill and Forrest article as a benchmark statement about career counseling, Remer and O'Neill present a decision-making model that encompasses the tenets of Type 4 counseling. The model has 13 sequential steps; the authors indicate the role of the counselor and the objectives for the client at each. The article discusses the potential impact of this self-directed, decision-making model on career counseling. Specific counseling outcomes are discussed along with anecdotal evidence that supports the power of the model to create these outcomes.     

Previous reward decreases errors of commission on later ‘No‐Go’ trials in children 4 to 12 years of age: evidence for a context monitoring account

Inhibitory control is widely hypothesized to be the cornerstone of executive function in childhood and the central deficit in a number of developmental disorders, including attention‐deficit/hyperactivity disorder (ADHD). However, recent evidence from adults indicates that performance on response inhibition tasks may primarily reflect non‐inhibitory attentional control (context monitoring) processes. Yet it may be that inhibition plays a more central role in childhood – a time when the architecture of cognitive processes might be more transparent due to wide variability in skill level. Here we directly test inhibitory and context monitoring explanations of task performance on a Go/No‐Go task in a large group of children 4–12 years of age. We conclude that traditional inhibitory conceptualizations of task performance on the Go/No‐Go task cannot account for our findings, calling into question evidence supporting a central role for inhibitory control in cognitive development or developmental psychopathology.     

The divergent effects of fear and disgust on unconscious inhibitory control

Previous studies have shown that negative emotional distracters impair conscious inhibitory control. Recent research has shown that inhibitory control can be triggered unconsciously; therefore, in Experiment 1, we aimed to investigate whether negative emotional distracters affect unconscious inhibitory control. Furthermore, in Experiment 2, we examined whether fearful and disgusting distracters have differential effects on unconscious inhibitory control. Participants were instructed to perform a masked Go/No-Go task superimposed on a negative or neutral image cue (Experiment 1) or on a fearful, disgusting or neutral image cue (Experiment 2). Results showed that negative emotional distracters impaired unconscious inhibitory control; furthermore, disgusting distracters impeded unconscious inhibitory control when compared to fearful ones. This study is the first to provide evidence that fear and disgust may affect unconscious inhibitory control differently. These results expand the understanding of the relationship between emotions and inhibitory control.     

Excitatory and inhibitory learning with absent stimuli

Three experiments showed that 2 associatively activated stimulus representations may engage in excitatory or inhibitory learning, depending on their temporal relationship. Experiment 1a suggested that simultaneously activated stimulus representations show evidence of inhibitory learning in an acquisition test. Experiment 1b showed similar evidence of inhibition in a summation test. Experiment 2 found that activation of 2 stimulus representations in a serial compound resulted in excitatory learning between the antecedent and the subsequent (forward) and inhibitory learning between the subsequent and the antecedent (backward). The results show the dynamic influence of temporal contiguity on mediated learning.     

Is ADHD a disinhibitory disorder?

Attention deficit hyperactivity disorder (ADHD) is widely theorized to stem from dysfunctional inhibitory processes. However, the definition of inhibition is imprecisely distinguished across theories. To clarify the evidence for this conception, the author relies on a heuristic distinction between inhibition that is under executive control and inhibition that is under motivational control (anxiety or fear). It is argued that ADHD is unlikely to be due to a motivational inhibitory control deficit, although suggestions are made for additional studies that could overturn that conclusion. Evidence for a deficit in an executive motor inhibition process for the ADHD combined type is more compelling but is not equally strong for all forms of executive inhibitory control. Remaining issues include specificity to ADHD, whether inhibitory problems are primary or secondary in causing ADHD, role of comorbid anxiety and conduct disorder, and functional deficits in the inattentive ADHD subtype.     

Whose Community are You Working for? A Change Agent Case Study

This article explores the role and responsibility of the community psychologist in creating change that could potentially harm the group they are meant to be in solidarity with. Drawing upon a 2‐year project with a Latinx Student Union at a public middle school in the Pacific Northwest, I examine the ethical dilemmas that arose when powerful stakeholders (school administration) changed the goals and intention of the research project without the consent of the low‐power stakeholders (the students). This narrative seeks to shed light on the dilemmas that come with being an ethical community psychologist (Balcazar, Garate‐Serafini, & Keys, 2004; Nelson, Prilleltensky, & MacGillivary, 2001; O'Neill, 1989), how these ethics can be compromised by one's identity, and what it means to work for/with/against one's community when deciding whether to stay with or leave a project.     

Zen Buddhism and the intrinsic value of nature

Part IIt is a perennial theme in the literature on environmental ethics that the exploitation of the environment is the result of a blindness to (or perhaps a refusal to recognize) the intrinsic value of natural beings. The general story here is that Western traditions of thought have tended to accord natural beings value only to the extent that they prove useful to humans, that they have tended to see nature as only instrumentally valuable. By contrast, it is said that a new, environmentally friendly understanding of the world would value nature ‘for its own sake’, would conceive natural beings as having intrinsic value. In the light of such an understanding, the oak tree, for instance, would be seen not merely as a source of timber or shade or as a decoration for the front lawn, but as valuable ‘in itself’, as having an intrinsic value that ought to be respected (see further, O'Neill 1993, chapter 2).     

Long-term positive and negative identity priming: Evidence for episodic retrieval

An episodic retrieval account of negative priming (Neill, 1997; Neill & Valdes, 1992) was evaluated in three experiments. Duringpractice, regular word pairs were presented to subjects differing numbers of times. The subjects named specific target words while they ignored specific distractor words. Following a 5-min retention interval, memory for practice was revealed:Test responses for target words exhibited positive priming that increased with increases in the number of times that the words had been attended. Test responses for distractor words exhibited either positive priming (Experiment 1) or negative priming (Experiments 2–3) that also increased with increases in the number of times that the words had been ignored. The type of priming that abstractors exhibited was determined by several contextual similarities between the practice environment, in which distractors were ignored initially, and the test environments, in which they were processed subsequently. Negative priming that spanned a 5-min interval, increased with increases in the number of times that a distractor was ignored, and was sensitive to contextual changes indicated that the direction of the effect was temporally backward because the test probe cued memory for earlier processing of the priming stimulus when the distractor had been ignored.     

Stop that! Inhibition,sensitization, and their neurovisceral concomitants

There is increasing evidence that the behavior of living systems can be conceptualized as a self-organizing dynamical system. Moreover, evidence suggests that inhibitory processes give these systems the flexibility that is necessary for efficient functioning in the face of changing environmental demands. The process of sensitization can be conceived as a breakdown of inhibitory neural processes that can lead to maladaptive, perseverative behavior. In this paper we describe a model of inhibition and sensitization from a dynamical systems perspective. We show that inhibition is important for adaptive behavior across a number of levels of system functioning. Using our work on attention, emotion, and anxiety disorders we show the importance of both central - for example gamma-aminobutyric acid (GABA)-ergic - and peripheral - for example heart rate variability (HRV) - inhibitory processes and how they may be linked by a network of neural structures that guide the organism from one state of relative stability to another.
