The Assessment Battery for Communication (ABaCo) was introduced to evaluate pragmatic abilities in patients with cerebral lesions. In the present study we present normative data for individuals aged 15-75 (N = 300). The sample was stratified by age, sex and years of education, according to ISTAT (Italian National Institute of Statistics) indications in order to be representative of the general national population. As performance on the ABaCo decreases with age and lower years of education, the norms were stratified for both age and education.The ABaCo is a valuable tool in clinical practice; the normative data provided here will enable clinicians to determine different kinds and specific levels of communicative impairments more precisely. The assessment of pragmatic abilities emerged as a central issue in the evaluation of patients with communicative impairments and related disorders in the early 1980s (e.g., Prutting, 1982), and the influence of pragmatic variables in treatment plans and goals has been more fully appreciated in the last 30 years. Pragmatic ability refers to a wide range of communicative behaviors concerning the way language is used in context to convey meanings (Adams, 2002;Bates, 1976; Kempson, 1975), and in the population of individuals with cerebral lesions, numerous patients have been found to have difficulties that lie principally with pragmatics. Patients typically show poor turn-taking skills and difficulty with topic maintenance, have problems understanding discourse and non-literal meanings, and may find it difficult to interpret subtle meanings or idiomatic statements and make knowledge-based inferences in social scripts (e.g., Dennis & Barnes, 1990; Friedland & Miller, 1998; McDonald, 1993). Moreover, people with brain injury often demonstrate normal basic linguistic skills, but have difficulty adapting their communication to specific ABACO -NORMATIVE DATA 4 contexts (e.g., different social situations or different communicative partners) and managing complex pragmatic phenomena, such as irony and deceit (Angeleri et al., 2008;Bara, Tirassa, & Zettin, 1997; Cutica, Bucciarelli, & Bara, 2006). The recognition of pragmatic components as a crucial feature in rehabilitation programs thus led to the need to deal with the pervasiveness of these communicative disorders and the consequent social isolation suffered by brain-injured individuals. Importantly, in a two-year follow-up study, Snow, Douglas, and Ponsford (1998) showed that pragmatic disorders do not spontaneously improve over time, providing evidence that communicative difficulties do not resolve as a consequence of recovery over time or speech-language input. These findings suggest that careful efforts should be made to identify and manage pragmatic disorders early on following brain injury. Finally, normative data offer the opportunity to operationalize pragmatic functioning within a normal range, and obtain a precise evaluation of domains of impairment, a crucial step in planning clinical pathways of recovery.
