A computer-aided digital audio recording and encoding system for improving the encoding of verbal reports

The increasing use of verbal reports in psychological research requires tools for improving the ease and reliability of collecting and coding verbal report data. An approach is described that maintains the verbal report data in digitally recorded audio form throughout the collecting and encoding processes. A new computer-aided encoding tool, CAPAS, is described, which randomly selects and plays individual protocol segments and stores computer keyboard-entered codes in an SPSS-formatted data file.     

The semantic specificity of gestures when verbal communication is not possible: The case of emergency evacuation

The aim of the present study was to examine the comprehension of gesture in a situation in which the communicator cannot (or can only with difficulty) use verbal communication. Based on theoretical considerations, we expected to obtain higher semantic comprehension for emblems (gestures with a direct verbal definition or translation that is well known by all members of a group, or culture) compared to illustrators (gestures regarded as spontaneous and idiosyncratic and that do not have a conventional definition). Based on the extant literature, we predicted higher semantic specificity associated with arbitrarily coded and iconically coded emblems compared to intrinsically coded illustrators. Using a scenario of emergency evacuation, we tested the difference in semantic specificity between different categories of gestures. 138 participants saw 10 videos each illustrating a gesture performed by a firefighter. They were requested to imagine themselves in a dangerous situation and to report the meaning associated with each gesture. The results showed that intrinsically coded illustrators were more successfully understood than arbitrarily coded emblems, probably because the meaning of intrinsically coded illustrators is immediately comprehensible without recourse to symbolic interpretation. Furthermore, there was no significant difference between the comprehension of iconically coded emblems and that of both arbitrarily coded emblems and intrinsically coded illustrators. It seems that the difference between the latter two types of gestures was supported by their difference in semantic specificity, although in a direction opposite to that predicted. These results are in line with those of Hadar and Pinchas‐Zamir (2004), which showed that iconic gestures have higher semantic specificity than conventional gestures.     

Spoken Narrative Assessment: A Supplementary Measure of Children’s Creativity

This study developed a spoken narrative (i.e., storytelling) assessment as a supplementary measure of children’s creativity. Both spoken and gestural contents of children’s spoken narratives were coded to assess their verbal and nonverbal creativity. The psychometric properties of the coding system for the spoken narrative assessment were investigated with 30 Cantonese-speaking children aged six to nine. The internal consistency and the intercoder agreement were good. In addition, children’s scores on the 3 coded variables were moderately correlated with their creativity-relevant skills as measured by Alternate Uses Task (Guilford, 1967) and subjective ratings of creativity provided by judges. Children with higher verbal skills, as measured by Similarities (The Wechsler Intelligence Scale for Children – 4th Edition (Hong Kong); WISC-IV HK), also scored higher in the speech composite of the coding system. The findings showed that the coding system of the spoken narrative assessment is reliable and valid for measuring children’s creativity objectively. An age-related norm will be established in future.     

The role of imagery in recognition memory for sentences

The effects of sentence imageability were examined in a test of continuous recognition memory following meaningful orienting tasks which emphasized verbal or imagery encoding. The results showed that distractors changed in syntactic form were more accurately identified for abstract than for concrete sentences, while memory for meaning was equally accurate for both sentence types. The orienting task manipulation did not affect this pattern of results. These data extend previous reports (Begg and Paivio 1969) by demonstrating qualitative differences in memory for concrete and abstract sentences when full comprehension of the stimulus material is required. The results are consistent with the dual coding hypothesis (Paivio 1971) but not with propositional models of memory (Anderson and Bower 1973).     

Perceptual scale expansion: an efficient angular coding strategy for locomotor space

Whereas most sensory information is coded on a logarithmic scale, linear expansion of a limited range may provide a more efficient coding for the angular variables important to precise motor control. In four experiments, we show that the perceived declination of gaze, like the perceived orientation of surfaces, is coded on a distorted scale. The distortion seems to arise from a nearly linear expansion of the angular range close to horizontal/straight ahead and is evident in explicit verbal and nonverbal measures (Experiments 1 and 2), as well as in implicit measures of perceived gaze direction (Experiment 4). The theory is advanced that this scale expansion (by a factor of about 1.5) may serve a functional goal of coding efficiency for angular perceptual variables. The scale expansion of perceived gaze declination is accompanied by a corresponding expansion of perceived optical slants in the same range (Experiments 3 and 4). These dual distortions can account for the explicit misperception of distance typically obtained by direct report and exocentric matching, while allowing for accurate spatial action to be understood as the result of calibration.     

Heuristic and statistical support for protocol analysis with SHAPA Version 2.01

This paper describes SHAPA Version 2.01, an interactive program for performing verbal protocol analysis. Verbal protocol analysis is a time-consuming activity that has hitherto typically been done by hand, whereas SHAPA represents an attempt to build a software environment to aid (but not replace) researchers in this activity. SHAPA allows researchers to develop an encoding vocabulary, to apply it to raw verbal protocol files, and to perform various types of data aggregation and data reduction. When performing verbal protocol analysis, researchers often try out different possible coding schemes before settling on the most effective one. SHAPA has been designed to support quick alterations to an encoding vocabulary and to support the rigorous statistical analysis of content and patterns (sequential data analysis) in protocol data. It is intended as an exploratory, as well as analytical, tool and has been designed to be easy for novices to learn and use, yet fluid and powerful for experts. A prototype version of SHAPA has already been used by a sample of researchers, and their experiences and requests have guided the programming of the present much more powerful version.     

Short- and long-term memory contributions to immediate serial recognition: Evidence from serial position effects

A long-standing body of research supports the existence of separable short- and long-term memory systems, relying on phonological and semantic codes, respectively. The aim of the current study was to measure the contribution of long-term knowledge to short-term memory performance by looking for evidence of phonologically and semantically coded storage within a short-term recognition task, among developmental samples. Each experimental trial presented 4-item lists. In Experiment 1 typically developing children aged 5 to 6 years old showed evidence of phonologically coded storage across all 4 serial positions, but evidence of semantically coded storage at Serial Positions 1 and 2. In a further experiment, a group of individuals with Down syndrome was investigated as a test case that might be expected to use semantic coding to support short-term storage, but these participants showed no evidence of semantically coded storage and evidenced phonologically coded storage only at Serial Position 4, suggesting that individuals with Down syndrome have a verbal short-term memory capacity of 1 item. Our results suggest that previous evidence of semantic effects on “short-term memory performance” does not reflect semantic coding in short-term memory itself, and provide an experimental method for researchers wishing to take a relatively pure measure of verbal short-term memory capacity, in cases where rehearsal is unlikely.     

Contrasting five different theories of letter position coding: evidence from orthographic similarity effects

Five theories of how letter position is coded are contrasted: position-specific slot-coding, Wickelcoding, open-bigram coding (discrete and continuous), and spatial coding. These theories make different predictions regarding the relative similarity of three different types of pairs of letter strings: substitution neighbors, neighbors-once-removed, and double-substitution neighbors. In Experiment 1, we used an illusory word paradigm and found that neighbor-once-removed similarity contexts resulted in fewer illusory word reports than substitution neighbors but more illusory words than double-substitution neighbors. In Experiments 2 and 3, we used a masked form priming technique with a lexical-decision task. The pattern of facilitation was as predicted by spatial coding but was incompatible with slot-coding, Wickelcoding, and both versions of open-bigram coding. These results provide further support for the SOLAR (self-organizing lexical aquisition and recognition) model of visual word identification.     

Physicians' nonverbal rapport building and patients' talk about the subjective component of illness

Physicians' nonverbal communication has sometimes been found to be associated with patients' affective satisfaction. Too little attention has been given, however, to the impact of these caregiver behaviors on patients' self‐disclosure. This paper examines the relationship between physicians' nonverbal rapport building and patients' disclosure of information related to the subjective component of illness. Twelve third‐year residents at a large teaching hospital were videotaped during interactions with patients (N = 34). These physicians' nonverbal communication behaviors were coded in the introduction and diagnosis segments of the interactions. Patients' verbal communication behaviors related to disclosure of information about the subjective component of their illnesses were coded across the same segments. Correlation analysis revealed significant relationships between physicians' use of some types of nonverbal behaviors and patients' subjective disclosure, as well as physicians' avoidance of negative facial behaviors and patients' disclosure about life beyond symptoms and structural barriers to wellness. Implications for understanding the role of physicians' nonverbal communication on health care outcomes are considered.     

言语编码和视空编码在时间—空间联结中的作用

时间和空间存在反应编码联合效应（spatial—temporal association of response codes effect, STEARC）,该效应的编码是视觉空间性还是言语性还存在争议。本研究借鉴Georges（2015）的研究方式,以2秒内的时距为刺激,实验1采用言语反应和空间反应,词语和空间与时距的关系分为一致和不一致。结果发现言语反应时,短时距用“左边”反应快,长时距用“右边”反应快,空间反应时,时距和空间的一致性效应消失,表明言语编码参与两种反应形式的STEARC效应。实验2将词语改为箭头朝向（视觉编码条件）,发现视觉编码和空间编码存在于相对应的反应形式中。研究表明时空关系的编码形式与具体任务要求有关。     

Improving the encoding of verbal reports by using MPAS: A computer-aided encoding system

The dramatically increased use of verbal report methodologies in psychological research has created a need for new tools to improve the efficiency and reliability of encoding these data. A computer-aided protocol encoding system called MPAS (Multiple Protocol Analysis System) presents individual protocol segments in a randomised order to one or more coders and then stores computer keyboard-entered codes for later output to an SPSS formatted data file. In the present paper, MPAS is described, and a brief example is provided of how MPAS can be used in a con-trolled laboratory study to rigorously analyze verbal protocol data.     

CowLog: Open-source software for coding behaviors from digital video

We have developed CowLog, which is open-source software for recording behaviors from digital video and is easy to use and modify. CowLog tracks the time code from digital video files. The program is suitable for coding any digital video, but the authors have used it in animal research. The program has two main windows: a coding window, which is a graphical user interface used for choosing video files and defining output files that also has buttons for scoring behaviors, and a video window, which displays the video used for coding. The windows can be used in separate displays. The user types the key codes for the predefined behavioral categories, and CowLog transcribes their timing from the video time code to a data file. CowLog comes with an additional feature, an R package called Animal, for elementary analyses of the data files. With the analysis package, the user can calculate the frequencies, bout durations, and total durations of the coded behaviors and produce summary plots from the data.     

Courtroom Interrogation of Rape Victims: Verbal Response Mode Use by Attorneys and Witnesses During Direct Examination vs. Cross-Examination1

The verbal behavior of attorneys and witnesses (rape victims) in direct and cross-examinations was coded according to a taxonomy of verbal response modes (VRMs). Significant differences were found between the verbal behavior of attorneys and witnesses on direct and cross-examination. The differences are those that would be expected on the basis of the advice given by legal authors concerning the techniques that should be used in the two types of interrogation. The VRMs reflect the different techniques that attorneys use in their efforts to influence juries' impressions of witnesses' credibility.     

Demand characteristics and research into drug use

Abstract

Health research makes frequent use of verbal reports; and such reports are usually assumed to be the surface indicants of measurable entities such as attitudes, beliefs, intentions, etc. which reside inside the person. It is our assertion that verbal reports themselves are motivated and variable; they are functional and context-dependent and their meaning and significance are localised. Consequently discourse cannot be treated as if it were fixed and categorical data to be retrieved from memory by asking questions that appear objective or disinterested. A method is postulated, using a social perception analogy with signal detection (SD) theory. The method allows for the assessment of subject criterion, and permits an examination of signal-strength in terms of the researcher's motivation. Data are evaluated in terms of their “robustness”, a measure which derives from the variability of response in different contexts, and under different elicitation procedures. The method requires few assumptions to be made about the “truth” or “falsity” of verbal reports. It focuses on the types of social activities that are performed by utterances and thus on the contextual variability revealed by asking questions in different situations and in different ways. This procedure does not presume a direct correspondence between verbal reports and mental representations.     

The on-line voyeur: Promises and pitfalls of observing electronic interaction

Studies that compare objective data on communication activity to data provided in verbal reports have indicated that verbal report data are not as accurate as one might hope. Researchers of communication have used verbal reports as their primary source of data because it presents a cheap and easy way to collect the data. This paper presents an easy alternative involving the study ofelectronic communication: a method that allows the collection of objective information on electronic communication, thus avoiding the problems associated with self-reports. The paper reviews the available literature on the accuracy of self-reports of communication, presents the instrument used to collect the objective electronic communication data, and discusses some of the difficulties and limitations encountered in implementing a study using the instrument.     

Can Spouses Provide Knowledge of Each Other's Communication Patterns? A Study of Self‐Reports,Spouses' Reports,and Observational Coding

The purposes of this study were (1) to assess individuals' self-reports of communication and their reports about their spouses' communication in order to examine the congruence of spousal views and (2) to investigate whether each report provided unique information about observed marital interactions. These associations were evaluated in a sample of 119 longtime married couples. The Verbal Aggression and Cooperation subscales from the Conflicts and Problem-Solving Scales were used as measures of negative and positive aspects of communication. The findings indicated that self-reports of both verbal aggression and cooperation were strongly associated with the same individual's report of his or her spouse's verbal aggression and cooperation. Conversely, self-reports were only moderately associated with reports made by spouses (e.g., the husband's report of his wife's communication). Hence, within-reporter agreement was higher than between-reporter agreement about marital communication. When entered into regression models, reports made by spouses, but not self-reports, explained unique variance in observations of marital hostility and affection. There was one exception: Wife self-report of verbal aggression explained unique variance in coders' ratings of wife hostility, controlling for husband report of wife verbal aggression. Findings indicate the importance of assessing partners' views of one another's communication for the most accurate portrayal of marital interactions. Implications for research and clinical work are discussed.     

Are early verbal communicative intentions universal? A preliminary investigation

This longitudinal study was conducted to provide preliminary information about the universality of early verbal communicative intentions. Three children whose native languages differ were videotaped in spontaneous mother-child interactions at 2-week intervals between MLU 1.0 and 2.0. The languages studied were American English, Danish, and Serbo-Croatian. Each child utterance was coded for the communicative intention expressed using a modified version of Dale's (1980) taxonomy. Findings indicate that all subjects used the full range of intentions. Overall, the intentions used most frequently were Naming and Attributes. Crosslinguistic similarities were also noted in patterns of intention usage as a function of increasing MLU. Results support the view that early verbal intentions are language-learning universals. However, no support was found for the universal-sequence hypothesis.     

Verbal reports of stimulus effects on learning: Introspection revisited

The accuracy of subjects' verbal reports on the respective causal roles of relevant and irrelevant stimulus factors on learning was investigated. In two experiments, university undergraduates learned strings of letters that were either grammatically structured or unstructured (a causal variable) and either color coded or black (a salient but irrelevant variable). Results indicated that subjects reported more causal impact of color than structure on the learnability of lists, despite the fact that the latter variable and not color had an actual effect on learning. It was proposed that verbal reports of stimulus effects on one's own behavior can be regarded as a task in estimates of covariation rather than direct retrieval of memory traces.     

Coding strategies and cerebral laterality effects

In a short-term recognition memory task, Ss were given relational imagery and rehearsal coding strategies in different sessions, with probes presented to the left or right cerebral hemisphere. Consistent with a model of separate processing systems for verbally and visually coded information, Ss yielded significantly faster response latencies for probes to the left hemisphere than the right when employing the rehearsal strategy, and significantly faster latencies for probes to the right hemisphere than the left when using the imagery code. This suggests that cerebral laterality effects are functionally related to coding strategies, and argues for the inclusion of imagery, or generated visual information, as part of the visual processing system. As such, generated visual information may be viewed as a coding alternative to verbal mediation.
