Grammaticality,Acceptability, and Probability: A Probabilistic View of Linguistic Knowledge

The question of whether humans represent grammatical knowledge as a binary condition on membership in a set of well‐formed sentences, or as a probabilistic property has been the subject of debate among linguists, psychologists, and cognitive scientists for many decades. Acceptability judgments present a serious problem for both classical binary and probabilistic theories of grammaticality. These judgements are gradient in nature, and so cannot be directly accommodated in a binary formal grammar. However, it is also not possible to simply reduce acceptability to probability. The acceptability of a sentence is not the same as the likelihood of its occurrence, which is, in part, determined by factors like sentence length and lexical frequency. In this paper, we present the results of a set of large‐scale experiments using crowd‐sourced acceptability judgments that demonstrate gradience to be a pervasive feature in acceptability judgments. We then show how one can predict acceptability judgments on the basis of probability by augmenting probabilistic language models with an acceptability measure. This is a function that normalizes probability values to eliminate the confounding factors of length and lexical frequency. We describe a sequence of modeling experiments with unsupervised language models drawn from state‐of‐the‐art machine learning methods in natural language processing. Several of these models achieve very encouraging levels of accuracy in the acceptability prediction task, as measured by the correlation between the acceptability measure scores and mean human acceptability values. We consider the relevance of these results to the debate on the nature of grammatical competence, and we argue that they support the view that linguistic knowledge can be intrinsically probabilistic.     

Grammaticality is inferred from global similarity: A reply to Kinder (2010)

Jamieson and Mewhort (2009b) proposed an account of performance in the artificial-grammar judgement-of-grammaticality task based on Hintzman's (1986) model of retrieval, Minerva 2. In the account, each letter is represented by a unique vector of random elements, and each exemplar is represented by concatenating its constituent letter vectors. Although successful in simulating several experiments, Kinder (2010) showed that the model fails for three selected experiments. We track the model's failure to a constraint introduced by concatenating letter vectors to construct the exemplar representation. To fix the problem, we use a holographic representation. Holographic representation not only provides the flexibility missing with the concatenation scheme but also acknowledges variability in what subjects notice when they inspect training exemplars. Armed with holographic representations, we show that the model successfully captures the three problematic data sets. We argue for retrospective accounts, like the present one, that acknowledge subjects' skill in drawing unexpected inferences based on memory of studied items against prospective accounts that require subjects to learn statistical regularities in the training set in anticipation of an undefined classification test.     

Maternal Treatment Acceptability and Preference of Room Time-Out and Deferred Time-Out Escape Contingencies

ABSTRACT

Maternal preference and acceptability were examined for two methods of addressing time-out escape behavior: room time-out (RTO) and deferred time-out (DTO). With respect to preference, mothers were split about evenly. Spanking frequency and previous effectiveness using privilege removal were associated with preference for DTO while previous effectiveness using RTO was associated with preference for RTO. Child age was negatively associated with acceptability for either treatment and lax parenting style was negatively associated with acceptability for DTO. Results suggest that DTO could provide an alternative escape contingency for mothers who spank their children or who have been unsuccessful using RTO.

Escape from freedom: Choosing not to choose in pigeons

Preference for the availability of food-reinforcement alternatives was investigated with Rachlin and Green's (1972) concurrent-chains self-control paradigm. The terminal link of one chain made available a choice between immediate access to food for T seconds and delayed access to food for 4 seconds. The terminal link of the other chain provided only delayed access to food. When T was reduced to .25 seconds, pigeons began to select the delayed-access key in both terminal links. Even so, the pigeons strongly preferred constraint over choice. This effect could not be accounted for by differences in the actual amount of food obtained in the terminal links, by avoidance of the immediate-reinforcement key when not presented as part of a choice, or by avoidance of a multi-key terminal link. Rather, constraint was preferred over freedom. Apparently, the preference for choice is determined by the particular type of choice offered.     

Violations of Expectations in Creativity and Perversion

Expectations and violations of expectations provide an entry into creativity and into perversions of aggression in the form of violence. Both creative works and perversions are co-created by a violator of expectations and one whose expectations are violated. The life of Kip Kinkel, a fifteen-year-old mass murderer illustrates the reciprocal violation of expectations between Kip and his parents leading to his increasingly perverse ways of asserting his presence in a world that was slipping from his grasp. Whereas the histories of some violent persons are replete with violations of expectations of living in a safe, predictable, affectively responsive world, a number of creative people (Stravinsky, Chagall, Wagner) began life as violators of the expectation of their families. They were stillborn or became so sick that they were not expected to survive, but they did. In their paintings and operas the theme of being violators of expectations then became dominant.     

Blacklisted: Boundaries,Violations, and Retaliatory Behavior in the BDSM Community

This qualitative ethnographic study sought to gain insight into how participants in the Bondage/Discipline/Sadomasochism (BDSM) community negotiate and maintain boundaries in order to engage in mutually satisfying BDSM activities. Additionally, this study explored how boundary violations are handled by a community stigmatized by the larger culture. Results indicated that participants employ methods to keep BDSM play ‘safe, sane, and consensual’, although boundary violations do occur. These violations are handled internally by appointed community members and participants may engage in retaliatory behavior, with the occasional member employing violence. Implications of the research and future avenues for exploration are discussed.     

Reducing Escape without Escape Extinction: A Systematic Review and Meta-Analysis of Escape-Based Interventions

Individuals with disabilities may engage in challenging behavior to escape aversive stimuli, like academic tasks or non-preferred foods. Interventions to reduce these behaviors often employ escape extinction; that is, the implementer withholds escape following challenging behavior. Escape extinction can increase risk of injury, restrict autonomy, and worsen the learner–implementer relationship. To mitigate collateral effects, interventions can use strategies without escape extinction (i.e., escape-based); that is, implementers can provide escape contingent on challenging behavior during intervention, in conjunction with other intervention components. However, no comprehensive syntheses of these interventions have been conducted. We identified 39 articles that included escape-based interventions, which contained 273 single-case designs. Escape-based interventions were associated with lower levels of challenging behavior and higher levels of adaptive behavior than baseline conditions. Most comparisons between escape-based and escape extinction interventions showed no functional relation, indicating that escape extinction may not add substantial benefit to intervention efficacy.

     

Escape from Twin Earth: Putnam's 'Logic' of Natural Kind Terms

Many still seem confident that the kind of semantic theory Putnam once proposed for natural kind terms is right. This paper seeks to show that this confidence is misplaced because the general idea underlying the theory is incoherent. Consequently, the theory must be rejected prior to any consideration of its epistemological, ontological or metaphysical acceptability. Part I sets the stage by showing that falsehoods, indeed absurdities, follow from the theory when one deliberately suspends certain devices Putnam built into it , presumably in order to block such entailments. Part II then raises the decisive issue of at what cost these devices do the job they need to do. It argues that - apart from possessing no other motivation than their capacity to block the consequences derived in Part I - they only fulfil this blocking function if they render the theory unable to deal with fiction and related 'make-believe' activities. Part III indicates the affinity Putnam's account has with the classically 'denotative' view of meaning, and thus how its weaknesses may be seen as a variant of the classical weakness of 'denotative' approaches. It concludes that the theory is a conceptual muddle.     

Nonverbal Expectancies and the Evaluative Consequences of Violations

This report reviews the construct of expectancy and its relevance to understanding communication phenomena. Given the shortage of empirically based knowledge about what constitute expected and unexpected interpersonal behaviors and how they are evaluated, a two-part experiment was conducted to determine the expectedness and evaluation of three nonverbal variables: touch, conversational distance, and posture. The possible moderating effects of communicator attractiveness, status, and gender were also examined. Respondents (N = 622) viewed photographs of an attractive or unattractive male or female stimulus interacting with a male or female partner, attributed to be of same, higher, or lower status, who displayed one of seven forms of touch or one of nine combinations of posture and proximity. Respondents rated the appropriateness, typicality, and desirability of the observed behavior. Results demonstrated that several behaviors are expected and positively valenced, while others qualify as positive or negative violations of expectations. Attractiveness influenced expectancies and evaluations; gender and status had limited effects. Implications for information processing and nonverbal expectancy violations theory are discussed.     

Action Interrupted: Movement and Breakpoints in the Processing of Motion Violations in Toddlers and Adults

From early in development, segmenting events unfolding in the world in meaningful ways renders input more manageable and facilitates interpretation and prediction. Yet, little is known about how children process action structure in events composed of multiple coarse-grained actions. More importantly, little is known about the time course of action processing in young children or about the specific features that recruit attention. This is particularly true when we consider action that pauses unexpectedly—as actions sometimes do—thereby violating the expectation of a continuous unfolding of motion. We assessed visual preference to intact and disrupted actions embedded within a multiaction event in toddlers and adults. In 1 condition, pauses were inserted at intact action boundaries, whereas in the other condition, they disrupted action. Attention in both groups was recruited to the disrupted relative to intact events. Time-course analyses, however, revealed developmental differences in sensitivity to the movement features (e.g., motion, pauses, and transitions) of disrupted events.     

ADHD and Judgments of Impulsivity in Rule Violations

Abstract

Participants with ADHD (n?=?45) and participants without ADHD (n?=?130, total n?=?175) judged hypothetical moral and conventional rule violations that varied the impulsivity of the act, the ADHD diagnosis, and the gender of the actor in order to examine (1) social reasoning about impulsiveness and (2) whether participants infer impulsiveness from the characteristics of the actor, including gender and ADHD-status. Moral violations were judged more negatively than conventional violations, even when they were impulsive. The characteristics of the actor influenced judgments in that participants judged boys’ behavior as more acceptable, as having less control, and as deserving of less punishment compared to girls. In addition, actors who were described as having ADHD were judged overall more positively. Participants with ADHD judged that all actors should receive similar punishment, regardless of the actor’s ADHD diagnosis, while participants without ADHD judged actors with ADHD should receive less punishment than those without.     

Acceptability of Time Out from Reinforcement Procedures for Disruptive Child Behavior:

Forty-eight teachers and forty-eight parents evaluated the effectiveness and acceptability of five behavioral procedures for reducing disruptive behavior in children. The results showed that teachers evaluated the procedures as being more effective and acceptable than did the parents. The treatment procedures rated as most effective and acceptable were reinforcement and isolation and contractual agreement. In additon, the procedures were rated as being more effective and acceptable for 5-year-olds than for 10-year-olds. The results of this study are compared to similiar studies reported by Kazdin.     

Unexpected inertial loading in rapid reversal movements: Violations of equifinality

In previous work using rapid horizontal positioning movements, unexpected inertial loads result in no shift in the final limb position, a result which has come to be known as the ‘equifinality principle’. In the present study, rapid single-joint reversal (i.e., sequential) movements were used, with enertial loads being either added or subtracted unexpectedly in two experiments. Contrary to the equifinality principle, the position of the reversal point was shortened if load was added, and lengthened if load was subtracted. These findings suggest that, unlike rapid positioning movements, sequential responses have an underlying temporal structure that causes the deviations from equifinality. These results do not agree with recent dynamical viewpoints for motor behavior in which such underlying temporal structures are supposedly absent.     

The Role of Consultations in the Prevention of Boundary Violations: Introduction to Panel

Lachmann's paper is reviewed as an essential statement of the implications of empirical infant research for psychoanalytic theory and technique, oriented by his intersubjectivist self-psychological perspective. His essay reflects the extent to which this application has come to maturity. This commentary elaborates several of his points: that infancy, basic psychopathology, and primitivity are not analogous; the emphasis on continuity in development; and the importance of social reciprocity and adaptation in early relationship and development. I note theoretical resonances to other psychoanalytic orientations, including developmental ego psychology, British object relations theory, contemporary Kleinian thinking, and, especially, the contemporary American relational movement.

Lachmann's clinical approach is then discussed as fitting into the overall relational emphasis on reciprocity and direct engagement in psychoanalysis. Within a framework of broad agreement, I wonder if Lachmann overemphasizes affirmative and idealizing selfobject relations at the expense of other transferences and mutual influence patterns. Finally, the theory of motivational systems is reviewed as an important innovation that does not go far enough in integrating dynamic systems theory.
